This study is about thermal enhancement in hybrid nano-ferrofluid. The conservation equations with thermo-correlations are solved numerically and computed solutions are used for parametric study related to flow of fluid and transfer of heat energy. The convergent solutions are derived via the finite element method (FEM). A mesh-free study is performed. Flow experiences a sufficient amount of resistive force by the porous medium. It is noted that Darcy porous is less resistive than Forchheirmer porous medium. It is also noted that convective heat transfer is compromised when the Forchheirmer parameter is increased. Dissipation effects are responsible for an increase in temperature and hence, an increase in thermal boundary layer thickness is noted. It is also observed that heat dissipation in a hybrid nanofluid is stronger than that in a nanofluid. The numerical values read the wall shear stress exerted by hybrid nanofluid is greater than wall shear stress by nano-ferrofluid. The wall shear stress increases as a function of the ferro-hydrodynamic parameter. However, the wall heat transfer rate (Nusselt number) decreases as the ferro-hydrodynamic parameter is increased. Similarly, wall shear stress increases versus Curie temperature number whereas Nusselt number decreases when the porosity parameter is increased. The porous medium is responsible for more wall shear stress on the surface. The transfer of heat in the presence of a porous medium in a fluid is greater than the rate of heat transfer in fluid in the absence of a porous medium. Viscous dissipation is responsible for the increase of the rate of heat transfer.

这项研究是关于混合纳米铁磁流体的热增强。对具有热相关性的守恒方程进行数值求解，并将计算出的解用于与流体流动和热能传递相关的参数研究。收敛解是通过有限元方法（FEM）导出的。进行无网格研究。流动受到多孔介质足够的抵抗力。值得注意的是，达西多孔体的电阻率低于Forchheirmer多孔介质。还应注意，当增加Forchheirmer参数时，对流传热受到影响。耗散效应是温度升高的原因，因此，注意到热边界层厚度的增加。还观察到，在混合纳米流体中的散热比在纳米流体中的散热更强。读取的数值由混合纳米流体施加的壁切应力大于纳米铁磁流体所施加的壁切应力。壁剪应力随铁水动力参数的变化而增加。但是，随着铁水动力参数的增加，壁的传热速率（Nusselt数）会降低。类似地，当孔隙率参数增加时，壁切应力随居里温度数增加，而努塞尔数减少。多孔介质负责表面上更多的壁切应力。在流体中存在多孔介质的情况下的热传递大于在不存在多孔介质的情况下在流体中的热传递速率。粘性耗散是导致热传递速率增加的原因。
