Force straight flow over an object of some geometry
Primarily used for displaying concepts of:
Streamlines Flow Separation Vortex Shedding
Top down view Variable flow speeds To be used for educational use Assist in fulfilling the ME department’s mission
4
Modular Transportable Variable test specimen geometry Adjustable angle-of-attack Variable flow from 1 to 12 in/s Adjustable flow height Adjustable nozzle section Laminar flow regime only Two main flow visualizers:
Ability to measure velocity through high speed camera and/or pulsing circuit Future adaptability for fluids other than water and different setups Will show concepts of flow separation, vortex shedding, and streamlines Possible potential for many other educational fluid dynamic purposes that the team
is not responsible for demonstrating (concepts of energy balance, conservation of mass flow, electrolysis, Bernoulli equation, baffle design, nozzle design, head calculations, and many more)

Possible Adjustments needed for Baffle Design
Baffle will initially not be permanently fixed to allow for
modifications
Feasibility calculations yielded max force on top plate of 5 lbf Baffle may need to be redesigned due to high pressure buildup Possible modifications include altering hole patterns/size,
creating a horizontal baffle design, or adding a plate in front of flow straighteners to distribute flow better

Feasibility was performed on a wide range of items. Due to time constraints all of them will not be addressed in this presentation. Some of the feasibility analysis’ and experiments performed include:
Pump calculations* Magnet calculations* Drain calculations (controlling flow)* Water supply calculations Electrolysis experimentation* Water table construction experiment Operating range analysis* Cart FEA analysis for strength Inlet flow force calculations Baffle design *Will be discussed in presentation

Step 1: Find flow rate
3in x 10in x 12in/s = 93.5 gpm
Step 2: Find power to overcome 2.5ft of head at the
Nominally ΔP=1.1psi
Step 3: Calculate Major Head Losses
Nominally ΔP=5.8psi
Step 4: Compare pump head needed to pump

Analyzed water table drain system as a circuit with
No resistance yields an outlet flow rate of 500+ gpm Therefore, modeling the system with pump and
Drain resistance is negligible
