Abstract

Abstract: Through theoretical analysis and numerical calculation, this paper analyzes the influencing factors, results and scope of the axial heat conduction on heat exchange tubes and shell cylinders. It obtained the formula for estimating the average axial temperature gradient of the cross section of heat exchange tubes and the formula for the effects of the axial heat conduction of heat exchange tubes and cylinder on the heat transfer of the main body. This provides a basis for rigorous heat transfer experimental research and engineering design.

Key words: axial heat conduction, wall temperature of heat exchange tubes and shell, heat transfer research & engineering design, numerical simulation
