The aim of this study is to examine the Darcy-Forchheimer flow = of H2O-based Al-Al2O3/Cu-Al2O3 hybrid nanofluid past a heated stretchable plate including heat consumption/ generation and non-linear radiation impacts. The governing flow equations are formulated using the Naiver-Stokes equation. These flow equations are re-framed by using the befitted transformations. The MATLAB bvp4c scheme is utilized to compute the converted flow equations numerically. The graphs, tables, and charts display the vicissitudes in the hybrid nanofluid velocity, hybrid nanofluid temperature, skin friction coefficient, and local Nusselt number via relevant flow factors. It can be seen that the hybrid nanofluid velocity decreased as the magnetic field parameter was increased. The hybrid nanofluid temperature tended to rise as the heat absorption/generation, nanoparticle volume friction, and nonlinear radiation parameters were increased. The surface drag force decreased when the quantity of the magnetic parameter increased. The larger size of the radiation parameter led to enrichment of the heat transmission gradient.
本研究的目的是研究基于水的Al-Al2O3/Cu-Al2O3混合纳米流体在受热可拉伸平板上的达西-福希海默流动,包括热消耗/产生以及非线性辐射影响。控制流动方程是使用纳维-斯托克斯方程建立的。通过合适的变换对这些流动方程进行重新构建。利用MATLAB bvp4c方案对转换后的流动方程进行数值计算。图表展示了混合纳米流体速度、混合纳米流体温度、表面摩擦系数和局部努塞尔数随相关流动因素的变化情况。可以看出,随着磁场参数的增加,混合纳米流体速度降低。随着热吸收/产生、纳米颗粒体积分数和非线性辐射参数的增加,混合纳米流体温度趋于升高。当磁参数的量增加时,表面阻力减小。辐射参数的较大值导致热传递梯度增大。
