Q3) In some wind tunnels the test section is perforated to suck out fluid and provide a thin viscous boundary layer. The test section wall in Fig.3 contains 12064 holes of 5 mm diameter. The suction velocity through each hole is V = 8 m/s, and the test section entrance velocity is V₁ = 35 m/s. Assume incompressible steady flow of air at 20°C, compute, Vo, V₂ and Vf in m/s. Test section D₁ = 0.8 m Uniform suction D₁= 2.2 m Do = 2.5 m V₂ -L=4m Fig.3 L V₁ Vo 4

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.
