The VKI has been actively involved in the design of turbo-
machinery components ranging from micro gasturbines,
axial/radial compressors/turbines, fans, pumps to internal
cooling channels for industrial clients and governmental
agencies.
To help the designer in his design process, the VKI has
developed over several years of experience a Computer
Aided Design Optimization (CADO) tool using numerical
optimization algorithms based on evolutionary algorithms,
surrogate models and high fidelity evaluation tools such as
Computational Fluid Dynamics (CFD) and Computational
Structural Mechanics (CSM). It is the perfect tool to improve
the performance of existing designs or for designing new
components. Innovative designs are produced in a reduced
time to market.

COMPUTER AIDED DESIGN OPTIMIZATION
OF TURBOMACHINERY COMPONENTS
MULTIDISCIPLINARY OPTIMIZATION
Designing turbomachinery components consists in the evaluation of
conflicting requirements emerging from different disciplines. As one
of the projects investigated at the von Karman Institute, the
optimization of internal cooling channels in a high-pressure turbine
is an example of complex design work involving trade-offs between
fluid process and structural integrity evaluated by conjugate heat
transfer computations.

U-bend optimized for minimal
pressure losses
Traditional design approaches in industry operate with several
iterations between different engineering departments, each one
evaluating design changes to improve the performances in their
specific disciplines. Multi-disciplinary optimization techniques
enable to reach a global optimum considering simultaneously the
conflicting requirements of all the different disciplines. By limiting
iterative design changes, an interactive design optimization process
reduces the time to market cost.
The current capabilities include aerodynamics, aero acoustics,
structural mechanics, vibrational mechanics and conjugate heat
transfer. Typical objectives include efficiency, range, and emitted
noise, while constraints are imposed on stall behavior, mechanical
stress limits due to centrifugal forces, thermal stresses and/or
pressure forces, etc.
