Abstract This paper is about entropy generation in Marangoni convective flow due to rotating disk with irregular heat source. Nonlinear mixed convection radiative flow is considered here. Exponential base heat source is addressed. Subsequent equations are transformed to the ODE's by using generalized Karman's variables. Results are found by using NDSolve MATHEMATICA. Through graphical illustration velocity, temperature, Bejan number and entropy generation are discussed. Axial velocity enhances via Marangoni number while temperature decays. Velocity is greater via larger nonlinear thermal convection parameter. Entropy rate boosts up for variation of nonlinear convection parameter and Marangoni number. Bejan number decays against Brinkman number and nonlinear convection parameter.

Marangoni 对流和不规则热源在熵优化耗散流中的传输

摘要 本文研究了不规则热源旋转盘在马兰戈尼对流中的熵产生。这里考虑非线性混合对流辐射流。指数基础热源得到解决。使用广义卡门变量将后续方程转换为 ODE。结果是通过使用 NDSolve MATHEMATICA 找到的。通过图形说明速度、温度、贝扬数和熵生成。当温度衰减时，轴向速度通过马兰戈尼数增加。通过更大的非线性热对流参数，速度更大。熵率因非线性对流参数和马兰戈尼数的变化而增加。Bejan 数随 Brinkman 数和非线性对流参数衰减。
