Abstract:

The chapter presents a method of simulating two-dimensional flow around airfoils at various angles of attack for the purpose of determining several aerodynamic conditions and coefficients. Basically the experimental method is as follows a hole in the shape of an airfoil cross section is cut in metal foil or other suitable conducting sheet. The winding of a toroidal electromagnet is passed through the hole perpendicular to the plane of the foil. After adjustment of the currents through the foil and winding it is possible by means of a probe and measuring instrument to map out the field grid of the simulated flow around the airfoil for identification of critical points, the boundary layer, fulfillment of the Chaplygin-Joukowski condition, etc. It is stated that the method is ideally adapted to lecture presentation and laboratory study.
