EFFECT OF HEAT TRANSFER ON THE BEARING PROPERTIES OF A FINITE SPAN WING AT SUBSONIC SPEEDS
摘要
Aerodynamic forces acting on finite span wing at subsonic speeds in the presence of heat transfer are investigated using the momentum conservation law for a continuous medium. An analytical expression for the principal vector of aerodynamic forces in view of heat transfer is obtained. The expression allows the effect of heat transfer on the bearing properties of the wing to be investigated. The numerical simulation results of the aerodynamic characteristics of finite span wings that have been obtained with commercial software in solving the Navier−Stokes equations are presented, which completely confirm the results of the analytical studies of the effect of heat transfer on the lift. An analytical estimate of the lift of a flat plate at a zero angle of attack when heating or cooling one of the streamlined surfaces was done.
