摘要
The flows in which thermal process plays an important role are discussed using the analytical method. An approximate expression for the variation of the stream-pipe cross-section with the temperature is obtained. Some basic properties of the thermofluid flow are dealt with, such as the phenomenon that the streamlines will "reject when heated and attract when cooled" or "attract when heated and reject when cooled" under different heat transfer conditions and the deviation of the sonic point from the point of the smallest cross-section area of the stream-pipe.
