摘要

本文研究了斜阶梯管内三维混合对流流动的不可逆性。为了达到这个目的，根据热力学第二定律对熵的产生进行了分析。详细分析了浮力对流动不可逆性的影响。结果表明，熵生成数和贝使数与格拉什夫数和风管倾角密切相关，且格拉什夫数对垂直风管的影响更大。

The Effects of Buoyancy Force on the Irreversibility of Three-Dimensional Step Flow in an Inclined Duct

This research deals with the study of the irreversibility of three-dimensional mixed convection flow in an inclined duct with step. To reach this goal, an analysis of entropy generation is carried out according to the second law of thermodynamics. The effects of buoyancy force on the flow irreversibility are analyzed with all details. The results show that the values of entropy generation number and Bejan number are intensively dependent on the Grashof number and duct inclination angle, so that the effects of Grashof number on the mentioned parameters are much higher for the vertical ducts.
