Major Challenges 15 Water Leak ¡ Problem: Water was leaking out of bulk head fitting due to uneven surfaces ¡ Solution: Used a Form-A-Gasket to create gasket for uneven surfaces Electrolysis ¡ Problem: Bubbles were created, but difficult to see ¡ Solution: Used underwater LED lights to emphasize bubbles by reflection of light
Flow Separation 16 According to theoretical results separation angle should occur approximately at 80 O from trailing end for 0.5 in/s flow velocity Separation angle using food dye was approximately at 80 O Separation angle using electrolysis was approximately at 80 O
Uniform Straight Flow Video 17 Uniform flow velocity throughout test section Distinct straight streamlines
Budget 18 Budget for project was $2000 Team spent ~$1800 Extra money was spent on buying additional replacement supplies such as platinum wire for future use
Future Design Recommendations 19 Modularity Design ¡ Completely redesigned to make setup easier Size of Water Table ¡ A longer and wider water table would allow for straighter flow and a larger test section capability Higher Voltage for Electrolysis ¡ More bubble generation ¡ Dangerous, but a cover could be made Deeper Water Design ¡ Deeper water design would allow the high mode on the pump to be used without it surging
