On the optimal location of the localized surface heating for increasing the laminar boundary gas layer stability and delaying he laminar-turbulent transition

The purpose of the article consists in determination of the surface heating optimal localized position and estimation of efficiency of such a principally new method of laminarization. The air flat composed laminar boundary layer on the non uniformly heated surface is considered. The Navier-Stokes, continuity and energy equations were used as mathematical models. It is shown that besides the grain in the degree of perturbations quenching, there takes place the shift of the heated section down the flow. The problem on economical advisability of laminarization of flying apparatuses on the account of localization heating is studied
