The effect of compressibility on two-dimensional tunnel-wall interference for a symmetrical airfoil

The effect of compressibility on two-dimensional tunnel-wall interference for a symmetrical airfoil

Date: January 1, 1943
Creator: Nitzberg, Gerald E
Description: Summary: The effective change in the velocity of flow past a wing section, caused by the presence of wind-tunnel walls, is known for potential flow. This theory is extended by investigation of the two-dimensional compressible flow past a thin Rankine Oval. It is shown that for a symmetrical section at zero angle of attack the velocity increment due to the tunnel walls in the incompressible case must be multiplied by the factor 1/1-M^2 to take account of compressibility effects. The Mach number, M, corresponds to conditions in the wind-tunnel test section with the model removed (p. 1.).
