Web Based Flow Visualization Facility Group Members: Justin Scott Sydni Credle Karen Davis Mentor: Dr. Shih

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.

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

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.

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

Mechanical Design Aspects Design of mobile camera mounts Design of synchronous linkage for laser/optical platform Motor Selection Linear bearing system

Mechanical Design Aspects (continued) Gear Analysis Loading Calculations Material Selection and Design Plumbing Design Setup and design of video recording equipment

Computer Related Aspects Remote instrument control via the Internet using LabVIEW programming Video studio design for the lab imaging Real time video and data streaming via the Internet

Real World Applications

Real World Applications (continued)

Conclusion Completed flow visualization system is a critical tool in the analysis of fluid mechanics. Integration of the physical laboratory with the Internet, in turn creates a virtual laboratory. The final deliverable will benefit educators, students, and industry.
