A Comparison between the Predicted and Experimental Characteristics of a NACA 64 sub 3-418 Aerofoil at Low Reynolds Numbers,
Abstract
This paper uses the computer program of Eppler & Somers (59 for low speed aerofoil design to obtain theoretical results for a NACA 64 sub 3-418 aerofoil in the Reynolds number range 300000 to 1000000. These predictions are compared with our recent experimental results. So far the agreement is poor for the lift and drag coefficients. The predicted positions of laminar separation are shown to agree reasonably well with experiment, although the predicted positions of turbulent reattachment and turbulent separation are in error. The program does have the facility to take account of aerofoil roughness and freestream turbulence. The predicted values appear to underestimate the measured effects of roughness.
