Project Description – Water Table Force straight flow over an object of some geometry to study fluid dynamic effects Primarily used for displaying concepts of:  Streamlines  Flow Separation  Vortex Shedding Top down view Variable flow speeds Laminar flow regime To be used for educational use Assist in fulfilling the ME department’s mission statement

ME Department Mission Statement The ME faculty have adopted the goal of establishing our department as one of the top 25 ME programs first in the nation, and then in the world. Based on a strategic planning retreat in May 2008, the faculty agreed that we, collectively as a department and in collaboration with others, should accomplish three tasks, in pursuit of our goal: Demonstrate a revolutionary advance in engineering education whereby we turn every entering student into graduates who achieve outstanding success. Provide solutions to three compelling problems of national and global significance. Other ME departments must emulate us. We must disseminate our model of education and research, and become the role model to which other institutions aspire.

Customer Needs

Functional Decomposition

Engineering Metrics/Specifications

House of Quality All specifications correspond to a customer need and vice versa

Initial Concept Generation Fluid Flow visualization Flow speed control Holding fixture for specimen Angle-of-attack fixture for specimen Water movement Water reservoir Flow meter Inputting water Expelling water Cart structure Flow straighteners Geometry of water table Test section material

Concept Selection Each task on functional decomposition was analyzed

Concept Selection Research was conducted to assess each concept Tables were used to assess concepts by comparing concepts with functions/parameters

Systems Model Top view on next slide…

Systems Model

Flow Analysis CFD in FLUENT, symmetry used Flow simulation at 1 ft/s (worst case for straightness) Conclusion: Flow at test section meets specification, uniform within about.1 ft/s

Electrolysis Feasibility Preliminary testing has been conducted to better understand power requirements and bubble flow. Results  Test 1 | Test 2 Test 1 Test 2  Electrolysis Test Clip Electrolysis Test Clip  Test 2: 24V w/ 4 Tsp.

Pump Feasibility Flow rate for 1ft/s through 3” tall and 10” wide test section  93.5 gallons per minute Estimated head between pump and table  3 feet  No pipe losses accounted for Power Output to fluid=Q*ΔP  0.07 horsepower Conclusion: 1/3 hp pump should be sufficient
