ABSTRACT

The concept is offered for flow control which is based on purposeful modification of fluid motion space scales near a surface. It is proven using the developed approach of imposed spanwise-regular thermal fields (temperature boundary condition) causing a boundary-layer response in a form of srtreamwise vortices of a given scale. Such flow structure modification is shown to result in the improvement of aerodynamic performance of a test model under conditions of correct correlation between basic flow and control parameters.
