本文研究了在滑移影响下磁流体动力学（MHD）传热流动的综合效应。熵产生的影响也进行了研究。利用Bvp 4c Matlab软件包求解了一组无维方程。给出了磁参数、滑移参数等流动参数对流速分布和温度分布的影响，并通过图形进行了详细的阐述。同时还研究了熵产生和熵流随Bejan数变化的表达式。所得结果表明，对于不同的值的滑移参数，贝扬数（Be）的λ> 1的减少，而相反的行为是注意到λ < 1。
In this article, combined effects of magnetohydrodynamics (MHD) heat transfer flow under the influence of slip over a moving flat plate are investigated. Effects of entropy generation are also examined. A set of non-dimensional resulting equations are solved by means of Bvp4c Matlab package. The role of flow parameters like magnetic parameter and slip parameter on flow velocity profile and temperature profile are presented and elaborated through graphs. The expressions for entropy generation and flow against Bejan number are also examined. The obtained results reveal that for various values of slip parameter, the Bejan number (Be) decreases for lambda > 1, whereas opposite behaviour is noted for lambda < 1.
