Asymptotical models of boundary layer flow control

Investigated are the local flows in the laminar boundary layers in the vicinity of heating elements. On the basis of asymptotical analysis, mathematical models are formulated and similarity parameters are found. Determined are the flow parameters providing flow control (separation, transition). Presented are the results of numerical and analytical analysis. Another method of the flow control is associated with the technology of new materials development. For example, porous metals allow use of passive control methods to influence boundary layer separation or laminar-turbulent transition.
