Abstract: | A method of designing wing airfoils in separationless flow with suction of a portion of the external flow and reactive jet injection from the rear of the body (the total pressure and the density in the jet are different from those in the freestream) within the framework of the ideal incompressible fluid model is proposed. It is shown that this method of active flow control makes it possible considerably to increase the airfoil lift as compared with the same airfoil with no suction or injection. Examples of the design of such airfoils in separationless flow are presented. The reliability of the results obtained is confirmed by a numerical experiment using the Fluent program. |
