Wind tunnel testing of U-shaped and rectangular prisms at two turbulence levels of incoming flow
Original language description
The paper presents the results of experimental wind tunnel testing of rectangular and U-shaped beams. The aerodynamic coefficients of drag and lift were measured together with the pressure coefficients on the surface test bodies of the beams in section. The results were compared for two intensities of turbulence of the incoming flow. Our observations generally indicate that the pressure distribution and aerodynamic forces are affected by the turbulence intensity of the incoming flow. Maximum lift forces are reduced by turbulent flow, and the drag coefficient is reduced when the flow direction is close to zero. However, turbulence can increase drag forces at higher angles of attack. The pressure distribution over the cross sections is drastically altered by turbulent flow. The mean suction pressure can increase by 83% at certain pressure taps. Turbulence intensity has little effect on windward pressure.
