Overview

Client Statement Background Information Specifications Camera Mount Design Work Breakdown Structure (WBS) Scheduling Complications and Solutions Goals for the Spring Semester Conclusion

Conclusion

• WBS and Schedule promoted team efficiency towards completion of project goals.

• Camera mount design and fabrication were priority this semester. Upon completion, testing and calibration can be performed.

• Team members now have an extensive working knowledge of the LabVIEW software.

• In developing the user interface, the major concern for team has been the "how" of the matter.

Complications and Solutions

• LabVIEW– Received older version, 5.1, when we were

supposed to receive 6.i.– Contacted manufacturer, National Instruments,

to rectify the situation (coming soon).– Unfamiliar with the LabVIEW programming

language.– Group members trained by attending

instructional seminars, using tutorial CDs and utilizing local COE users.

Complications and Solutions (cont’d)

• VC-C3 Camera– Through research, we found it was too

expensive.– Ordered interim software and components

(Intel Camera and Microsoft NetMeeting Software).

– Recently received client approval to order the VC-C4 version of the camera.

• Web Page (live video streaming)– Underestimation of the task at hand.– Actively sought out professionals

• Dr. Van Dommelen

• Third floor Webmasters

• NetMeeting representatives

Complications and Solutions (cont’d)

Objectives/Client Statement

•Design and build a towing tank facility and the associated imaging process.

•Provide visualization enhanced information to supplement the teaching of fluid mechanics.

•Create computer interfaced instrument control for remote operation via the Internet.

IntroductionLearning/teaching Thermal Fluids is complex.

Distance learning purposes

Pre-lab student aid

Master each component separately

Move at own pace

Real world applications

Background Information

• A “fluid” is a substance that readily flows under applied shear (gases, liquids i.e. water, alcohol, gasoline).

• Fluids can’t be detected by the human eye, therefore, the concepts behind fluid mechanics prove to be very difficult to learn.

• Use of flow visualization to take out the guess work from the phenomena.

LabVIEW Interface

What is LabVIEW?

• Laboratory Virtual Instrument Engineering Workbench

• Automation and Control of Equipment• “G-programming”

• Creation of programs using graphics• Pictorial Block Diagrams instead of long

lines of syntax• Straightforward data flow methodology

LabVIEW User Interface•“Front Panel”•Knobs, Buttons, graphs, etc.•User Input using mouse and

keyboard

Graphical Code•“Block Diagram”•Constants, built-in functions, program execution control structures•Wires denote data flow

Simple example: Ideal cylinder Vs. Real world cylinder

Ideal circular cylinder experiencing 2-D flow of a uniform stream

Figure (left) shows symmetrical stream lines and no drag force.

Real circular cylinder experiencing a non-uniform flow

Figure (right) depicts the flow separation, creating a wake
