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 freepath 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.
