SINOPSIS

The results of an experimental investigation on the effect of heating the nose part of a flat plate model in relation to the development of the boundary layer and the laminar-turbulent transition are presented. On the basis of processing the velocity and temperature profiles in the laminar, transitional, and turbulent flow regions, the integral and statistical characteristics of the boundary layer at different heating regimes are determined. The influence of heating on the reduction of the local and total friction coefficients is estimated. The effect of the friction coefficient reduction is determined by the laminar-to-turbulent transition delay. The experiments were carried out in the T-36I wind tunnel at TsAGI at a flow velocity of 57 m/s and a flow turbulence of 0.06%.
