摘要:

本文采用最优同伦摄动法(OHPM)求解非线性磁流体动力学杰弗里-哈梅尔流与传热问题的解析近似解。Navier-Stokes方程考虑麦克斯韦电磁学和传热学,推导出两个非线性常微分方程。通过OHPM获得的结果与数值结果及同伦摄动法(HPM)结果对比显示具有很好的一致性。

英文摘要:

In this paper, Optimal Homotopy Perturbation Method (OHPM) is employed to determine an analytic approximate solutions for nonlinear MHD Jeffery-Hamel flow and heat transfer problem. The Navier-Stokes equations, taking into account Maxwell's electromagnetism and heat transfer lead to two nonlinear ordinary differential equations. The obtained results by means of OHPM show a very good agreement in comparison with the numerical results and with Homotopy Perturbation Method (HPM).
