In tnis paper an analytical method is proposed to predict the distribu-tion of the rate of entropy generation per unit volume in the boundary layer by means of the simultaneous solution of continuity, momentum, energy and entropy differential equations. Air is taken as an example to investigate the effects of the local Reynolds number, the Eckert number and the ratio of characteristic temperature difference to wall temperature on the distribution of the entropy generation in laminar boundary layer along a flat...

In tnis paper an analytical method is proposed to predict the distribu-tion of the rate of entropy generation per unit volume in the boundary layer by means of the simultaneous solution of continuity, momentum, energy and entropy differential equations. Air is taken as an example to investigate the effects of the local Reynolds number, the Eckert number and the ratio of characteristic temperature difference to wall temperature on the distribution of the entropy generation in laminar boundary layer along a flat plate. In addition, the rules that govern the change of entropy generation by conductive heat transfer and viscous dissipation are also discussed in this paper.This paper may offer some aids to understand the mechanism and the distribution of entropy generation as well as to overcome the irreversibility so as to provide menas for fully-utilizing the energy in the process of convective heat transfer.

The mechanism of enhaneed nucleate boiling in a tubs handle was investigated by electrodiffusion methed. The boiling heat transfer coefficient was suposed to he the sum of microlayer conductive heat tronsfer coefficient and convective heat transfer coefficient. The enhancement of heat transfer in the tube bundle was due to the efect ef beth microlayer conduction and bulk fluid envectien. The higher the heat flux of lower tubes, the higher the rate of heat transfered to upper tubes by mierolayer conduction. Microlayer conductive heat transfer cenfficient increased with the increase of pressure, but convective transfer coefficient appeared to be independent te the pressure.
