Abstract : A theoretical law of resistance in the turbulent boundary layer of a gas with non-gradient flowpast of a plate is developed. The existence of a limiting form of the resistance law is demonstrated, corresponding to very high Re numbers and self-similar relative to the turbulence constants and the physical properties of the viscous sublayer. Even the first approximation of the theoretical formula takes into account the influence of Re on the relative change in the friction coefficient with the temperature factor. This new theoretical law of resistance for a turbulent boundary layer with non-gradient flow-past of a plate does not require the introduction of any additional empirical coefficients or any special hypotheses associated with the nonisothermal nature and the compressibility of a gas flow.
