Heat transfer from a sphere in the intermediate dynamics region of a rarefied gas

The results are given of the experimental study of convective heat transfer from a sphere in a low-density subsonic stream. Generalizing the results obtained and earlier known data for sub-and supersonic velocities, we suggest approximate formulas for calculating heat transfer from a sphere under any streamline flow conditions of a rarefied gas.Moscow.
