Abstract
A technique for numerical calculations of the coefficients of temperature restitution and heat transfer on the surface streamlined by a high-speed constant-composition flow is suggested. The data obtained in the course of numerical studies of local coefficients of temperature restitution and heat transfer on this surface in the presence and absence of the longitudinal pressure gradient are given. The nonmonotonic variation of the coefficient of restitution along the streamlined surface length is established. We are the first who succeeded in obtaining the data on influence of both the adverse and accelerating longitudinal pressure gradients upon the coefficients of temperature restitution and heat transfer in a high-speed turbulent gas flow. Also obtained are some data on the influence of inaccurate determination of restitution coefficients upon heat transfer.
