Abstract Computational analysis was performed to scrutinize the MHD hybrid nanofluid free convection with combination of entropy generation within a permeable tank. Flow pattern was reported for wide range of scrutinized parameters. Outputs reveal that convective flow intensity augments with rise of permeability and stronger thermal plume generates. Isotherms reveal that growth of Lorentz force leads to less intensive heating and isotherm with less distortion appears. Insertion of magnetic field makes weaker convective flow and lower temperature gradient. As temperature of heat source reduces with rise of Hartmann number, Nuave decreases and greater exergy loss occurs. Lower surface temperature is achieved with rise of permeability of zone which is led to greater Nuave.

洛伦兹力对多孔罐内混合纳米流体的影响，包括熵产生

摘要 进行计算分析以仔细检查 MHD 混合纳米流体自由对流与可渗透罐内熵产生的组合。流动模式报告了广泛的仔细参数。输出显示对流强度随着渗透率的增加和更强的热羽流的产生而增加。等温线表明，洛伦兹力的增长导致加热强度降低，出现变形较小的等温线。磁场的插入使对流变弱和温度梯度降低。随着哈特曼数的增加，热源温度降低，Nuave 降低，产生更大的火用损失。较低的表面温度是随着区域渗透率的升高而实现的，这导致了更大的 Nuave。
