For your MQP project you are asked to study fluid (wind) flow over the tall cylinder shaped smokestack near Boynton Hall on the WPI campus. Cylinders (or smokestacks) in a fluid flow shed rotating fluid (vortices) at some shedding frequency f (in rad/sec) which is the dependent variable in this problem. Other important physical parameters include the fluid density p, the cylinder diameter d, and the oncoming wind speed V. Use p, V and d as repeating variables. There is one important physical parameter missing from my physical description. Name it. Hint: This is an external, viscous, incompressible flow. Also, ignore the smokestack height H and the taper (change in diameter) of the smokestack as important parameters for this test. Use your complete list of physical parameters to complete a dimensional analysis to find two II groups (non-dimensional parameters) that govern this problem. Since performing measurements on the WPI smokestack is difficult (and rather dangerous), you decide to perform experiments on a smaller cylinder in the WPI wind tunnel. The WPI smokestack has an average diameter of 8 feet, and the wind speed over the WPI smokestack is 10 mph. A 2 inch diameter cylinder is used to properly model the smokestack flow in the tunnel. c. What is the required wind tunnel air velocity

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condit…
