ASYMPTOTIC MODELS OF BOUNDARY LAYER FLOW CONTROL

摘要

Investigated are local flows in the laminarrnboundary layers in the vicinity of heatingrnelements. On the basis of asymptotical analysisrnmathematical models are formulated andrnsimilarity parameters are found. Determinedrnare flow parameters providing flow controlrn(separation, transition). Presented are results ofrnnumerical and analytical analysis.rnAnother method of the flow control is associatedrnwith the technology of new materialsrndevelopment. For example, porous metals allowrnuse of passive control methods to influencernboundary layer separation or laminar-turbulentrntransition
