1 VirtuLab: Web Based Flow Visualization Facility Final Presentation Team 6 Members: Justin Scott Karen Davis Sydni Credle Mentor/Client: Professor: Dr. Shih Dr.Luongo December 7, 2000

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

3 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 In developing the user interface, the major concern for team has been the "how" of the matter. Conclusion (cont’d)

6 Spring Semester Goals Project Schedule

7 Goals for the Spring Semester Web Page Design  Incorporate LabVIEW programming into design  Embed live video streaming  Background and procedure for experiment  Upload class deliverables for public use

8 Spring Semester Goals (continued) LabVIEW  Acquire LabVIEW version 6.i  Train team members to use 6.i  Final experiment interface design (educational module)  Consolidate motor controller functions into one program  Control via the Internet

9 Spring Semester Goals (continued) VC-C4 Web Cam  Order and acquire the VC-C4 camera from Canon, Inc.  Train team members to use VC-C4 web cam software  Create LabVIEW program to automate the control of the web cam  Research WebVIEW software

10 Spring Semester Goals (continued) Existing Experiment Set-up  Preliminary test of system  Performance Analysis  Design Modifications  Calibration  Final Testing

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 (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.

13 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)

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 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.

17 System Set-up Remote Users Physical Laboratory (motor controller) LabVIEW Interface

18 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

49 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.

50 Conclusions Comprehension of problem statement has been achieved Upon of completion of camera mount fabrication, can proceed with simulation/testing of the towing tank Next: Modifying and calibrating the existing system

51 Conclusions More complete comprehension of problem statement has been achieved Can proceed with fabrication of camera mount design Testing and calibration of existing system, leading to system modifications

52 Conclusions Current Status is Favorable (We’re On Point!!!!) Primary Concern Involves Logistics Implementation

53 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.
