The paper presents an analysis of heat transfer on the surface of a blunt cone of low elongation, streamlined at an angle of attack, which is based on systematic numerical solutions of the equations of a three-dimensional laminar boundary layer. The main attention in the work is paid to the study of the influence exerted on the intensity of heat exchange by the Mach and Reynolds numbers, as well as by the temperature of the cone surface. It is pointed out that in recent years there have been no literary publications devoted to the solution of three-dimensional equations of the boundary layer, which is associated with the emergence of the possibility of solving problems of this kind within the framework of the Navier–Stokes equations. At the same time, the validity of carrying out studies of heat transfer within the framework of three-dimensional equations of the boundary layer for the case of flow around bodies of a simple geometric shape is noted.
