Abstract : The problem of heat exchange at low pressure is treated. The following deviations from the classical method of studying heat exchange are presented: (1) as the characteristic dimension used in calculating the Grashof criterion, the authors took the distance equal to the sum of the diameter of the specimen and twice the mean free-path length of the molecules; and (2) they used the concept of an equivalent layer of a stationary gas possessing the same resistance to heat exchange as the convective boundary layer.
