3
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.

4
Conclusion (contd)

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

11
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.

12
Complications and Solutions (contd)

• 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.

13
Complications and Solutions (contd)

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

14
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.

15
Introduction

• Learning/teaching Thermal Fluids is complex.
• Distance learning purposes
• Pre-lab student aid
• Master each component separately
• Move at own pace
• Real world applications

16
Background Information

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

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

19

• 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

20
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
