Abstract
We present the results of an investigation into the roughness elements of a wing profile on the transfer of heat and aerodynamic resistance of a plate and a tubular surface. Criterial formulas have been derived for the calculation of the heat transfer and resistance. An evaluation of the efficiency of these tubes has demonstrated that knurling the roughness elements will serve to reduce the heat-transfer surface by 40% relative to that of a smooth surface.
