FINAL PROGRAM

Dear Turbine Blade Tip Workshop and Symposium 2013 Participants,On behalf of the ASME IGTI Board, our Chairperson, Professor Karen Thole, and the entire ASME IGTI staff, I would like to welcome you to ASME TBTS 2013. While we recognize ASME Turbo Expo as the premier forum for exchanging the latest prog-ress in turbomachinery technology, the ASME IGTI Board has been seeking other means for the diversification and globalization of technical exchange and per-sonal networking. TBTS 2013 represents one such diversification in the form of a hybrid workshop and symposium centered on a fairly narrow topical area to cre-ate a small and very focused event. This forum is modeled after similar techni-cal paper symposiums held by the International Center for Heat and Mass Trans-fer, as well as the well-known von Karman Institute lecture series workshops.

By combining both a symposium and a workshop together, we hope to provide a choice of content that will serve everyone from those just beginning in the field to those that are experts. The two-day workshop will deliver interactive lectures concern-ing the design, operability, aerodynamics, heat transfer, computational predictions, and treatments specifically for high-pressure turbine blade tips. A two-day symposium will build upon the lecture series with current proposed or enacted solutions, studies to gain insight to the physics, and a panel session for open discussion at the end. Topics include turbine blade tip steady and unsteady aerodynamics, blade tip heat transfer, in-ternal, external, and film cooling, shrouded and non-shrouded blade tip design, clear-ance effects, surface treatments, and new or modified designs and innovations. The symposium has 26 full technical papers that will be presented in single session format through the two days.

In addition, at the end of the first day of the symposium, the AIAA-ASME Student De-sign Competition will be concluded with the final presentation group that was unable to attend Turbo Expo.

We are delighted to have chosen Hamburg as our host city for this event. Hamburg is a thriving industrial city, the largest port in Germany, and also home to many cultural and arts attractions. Like most German cities, getting out and about in the evenings after the workshop and symposium should be fairly convenient.

Thank you all for attending this first-of-a-kind TBTS workshop and symposium. I hope that you will find your time in Hamburg to be an enriching and memorable experience.

FINAL PROGRAM

Session I Engine Tip Clearance Design Issues and Possible Solutions Boris Glezer, Optimized Turbine Solutions

Maintaining minimal blade tip clearance is one of the most critical requirements for achieving high perfor-mance and reliable operation of every gas turbine engine. Presented lecture provides details of complex rotor-to-stator displacements during various modes of transient and steady state operation of an engine. The lecture underlines different tip clearance related design criteria for airborne and industrial engines, ad-dressing also specifics of aeroderivative industrial engines. Conventional and non-traditional design meth-ods of passive, active and semi-active tip clearance control are reviewed for potential applications in both aircraft and industrial engine environment. Examples of analytical predictions of transient tip clearances and their experimental validation using various tip clearance measurement techniques are also reviewed.

Dr. Boris Glezer is an ASME Fellow and the former Chief of Turbine Cooling Design and Analysis at Solar Turbines. Over the years Boris has been awarded 18 patents, published over 40 professional articles and a few monographs, including a chapter on turbine cooling in the DOE Handbook of Turbomachinery. For many years he closely collaborated with a number of leading US universities addressing the most critical issues in turbine cooling design and blade tip clearance control. His background in the field included a 20 year career with Solar Turbines, where he was leading hot section cooling development with extensive heat transfer experimental and numerical studies, as well as design implementation of new cooling techniques. His pro-fessional career also includes three years of leadership in turbine design for propulsion of liquid rockets at Aerojet, and more recently consulting in his engineering firm Optimized Turbine Solutions.

Session II HP Turbine Blade Tip Aerodynamics John Coull, University of Cambridge

This lecture focuses on the key aerodynamic issues surrounding the tip design of high pressure turbine blades, with a view to the multidisciplinary problems facing the high pressure turbine designer. The leakage flow for a plain-tip blade is examined in detail to introduce the key underlying physics. Various strategies for reducing the leakage losses are then discussed: three-dimensional blade design, cavity tips, attached shrouds and winglets. The aerodynamic performance achievable with such strategies is discussed along with the thermal and mechanical issues that must be considered in the design process.

Dr. John Coull obtained his undergraduate and masters degrees in Engineering from Cambridge University, before completing his PhD at the Whittle Laboratory. He is now the Rolls-Royce Research Fellow at the Whittle Lab, covering turbine aerodynamics and heat transfer. His primary areas of research are unshrouded tip design, boundary layer transition and preliminary design methods.

FINAL PROGRAM

Session V Transonic Tip Heat Transfer and Aero Loss Li He, University of Oxford

The present lecture is largely based on the recent work on transonic blade top aerothermal performance, carried out at Osney Lab, University of Oxford. There have been many past efforts in researching turbine blade tip aerothermal behavior and characteristics, forming the basis of the conventional wisdom in rotor blade tip designs. The main issue of interest is: to what an extent would the conventional wisdom based on low speed tip aerothermal characteristics be applicable to a transonic blade tip? Furthermore, if a transonic tip does behave in a distinctive manner, can we potentially make use of this behavior in blade tip designs?

Prof. Li He holds the Rolls-Royce/Royal Academy of Engineering Chair of Computational Aero-thermal En-gineering, and had been the head of Osney Laboratory at Oxford University. His main research interests and experience are in modeling, design and optimization of unsteady aerodynamics, aero-elasticity and heat transfer in turbomachines. Li He has been a keynote speaker, vanguard chair for several international conferences, and a guest editor for the international journal of computational fluid dynamics. His work has been funded by the UK government, EU and gas turbine power generation industry, and he has acted as a consultant for several gas turbine steam turbine and aero-engine companies. He is a Fellow of American Society and Mechanical Engineers and Fellow of the Royal Aeronautical Society.

Session VI Blade Tip and Shroud Surface Treatments John Bolger, Rolls Royce This lecture will describe the typical blade tip and casing liner surface treatments employed in modern gas turbines. For lower temperature applications, nickel-based honeycomb liners are a common choice and are often found in low pressure turbines. For more arduous applications, metallic and ceramic liner materials are a widely used, with blade tips often coated with hard particles to perform a smooth cut and reduce the likelihood of blade wear during rub events. Fundamental to the choice of a surface coating solution will be the choice of a design policy of ‘no rub’, ‘just kiss’ or ‘rub-in’. A fully abradable rub-in system has the potential to allow for tighter running clearances by reducing some of the tolerance effects seen in real engine geom-etries and so is an attractive option. Such systems require extensive materials development programmes to deliver the desired characteristics in the engine environment and these programmes will be described in the subsequent sections of this lecture. Dr. John Bolger is the Chief of Turbine Aerothermal Engineering at Rolls-Royce Plc and has global responsi-bility for turbine aerodynamics and cooling. He is a Rolls-Royce Engineering Associate Fellow in Compressor Aerodynamics and he has led and developed the aerothermal technology and design of fans, compressors and now turbines on many Rolls-Royce gas turbine products over the last 23 years. In 2011, he moved to the hot end of the engine and is leading the aerothermal research, design and development of the first produc-tion application of a shroudless HP turbine blade in a Rolls-Royce Trent engine.

Session VII Computational Predictions for Blade Tips Ali Ameri, The Ohio State University

The presentation will outline the importance of tip clearance flows and their impact on the efficient opera-tion and the longevity of high pressure turbines. Computational means of flow analysis which include meth-ods of flow-domain discretization, application of numerical schemes, and effective utilization of turbulence models will be briefly surveyed. Computational modeling allows efficient analysis of tip treatments and evaluation of the losses and heat transfer rates. A survey of various types of tip treatments and their predicted effects will be presented. Additionally consideration will be given to supersonic flow effects in the turbine tip clearance passages as well as unsteady heat transfer effects on the tip and casing.

Dr. Ali Ameri is a research engineer with the Ohio State University. He has been working at the NASA Glenn Research Center where he has been performing computational work involving gas turbine heat transfer and aerodynamics for over 20 years. He is also engaged with OSU’s research efforts in gas turbines. He has authored many NASA reports and also has had many contributions to the ASME IGTI and the ASME Journal of Turbomachinery. Dr. Ameri is a Fellow of the ASME.

Session VIII Aerothermal Characteristics of the Blade Tip and Near-tip Regions of a Highly Loaded Transonic Turbine Blade

Wing Ng, Virginia Polytech and State University

The effect of tip leakage flow on the tip and near-tip heat transfer distribution has been studied on a flat tip turbine blade. The studies have been performed at various tip gap sizes (1% and 2%) and exit Mach numbers of 0.85 and 1.0. Using a combination of thin film gauges and IR technique, the spatial blade surface heat transfer coefficient distribution was obtained. In addition, numerical modeling (CFD) using commercial code ANSYS Fluent has been used to further characterize the tip region aero-thermal characteristics. The results, which are discussed in detail in this presentation, indicate that increasing the exit Mach number/Reynolds number significantly increases heat transfer on the blade tip and near-tip region. The flow within the tip gap flow reaches supersonic levels causing a shock system in the tip gap that influences the heat transfer on the tip surface. The upstream tip surface x/Cx < 0.4 is more sensitive to tip clearance effects compared to downstream tip surface. On the near tip surfaces, the stream-wise as well as span-wise influence of the leakage flow has been analyzed with results showing that the Mach number/Reynolds number effects can cause nearly 15% increase in heat transfer on the near tip surface

Prof. Wing Ng is the Chris Kraft Endowed Professor in Mechanical Engineering at Virginia Tech, where he has conducted research for nearly 30 years. Dr. Ng’s research expertise is in heat transfer in aero-propulsion sys-tems and gas turbine engines. He has given many invited lectures on his research, both in the US and abroad. As faculty, Wing Ng has also received several awards for teaching and research. He has over 200 publications in the areas of turbo-machinery and propulsion, and has received several best paper awards from ASME and AIAA. He has served as Technical Editors for several Journals for both of these professional societies, and he is a Fellow of the ASME and an Associate Fellow of AIAA. Ng is also active in serving the US government, and had given expert testimony to the US Congress relating to US aerospace industries, as well as served on vari-ous advisory committees for NASA and the Department of Defense.
