To become familiar to conventional pressure measuring instruments 2. A pressure tab is attached to the wall of the wind tunnel before the test section and connected to another manometer which gives static pressure reading.
If the adverse pressure is not too great, the boundary layer fluid can flow into slightly increasing pressure region from C to the trailing edge in Figure 4a without separating from the surface.
Surface pressure distributions Cp for inviscid flow and boundary layer. Figure 2 1 Circular cylinder, 2 Test section, 3 Prandtl manometer, 4 Betz Manometers, 5 Honey comb, 6 Nylon screens, 7 Wall Pressure Tap, 8 Diffuser, 9 Fan 2 In the second set-up a blower at the inlet section causes the air flow through the wind tunnel.
The fluid exerts pressure on the front half of the cylinder in an amount that is greater than that exerted on the rear half.
Tighten the set screw using screw driver. Laboratory Report 1. Consider a circular cylinder immersed in a uniform flow.
To obtain and compare theoretical and experimental surface pressure distributions on a circular cylinder. Straighteners: The purpose of the straighteners is to straighten the airflow. The wall static pressure p is measured by a Betz Manometer and pressure around the cylinder pc is measured by Prandtl manometer.
Only the first 10 taps are connected.
