Within fluid mechanics, the flow of hybrid nanofluids over a stretching surface has been extensively researched due to their influence on the flow and heat transfer properties. Expanding on this concept by introducing porous media, the current study explore the flow and heat and mass transport characteristics of hybrid nanofluid. This investigation includes the effect of magnetohydrodynamic (MHD) with chemical reaction, thermal radiation, and slip effects. The nanoparticles, copper, and alumina are combined with water for the formation of a hybrid nanofluid. Using the self-similar method for the reduction of Partial differential equations (PDEs) to the system of Ordinary differential equations (ODEs). These nonlinear equation systems are solved numerically using the bvp4c (boundary value solver) technique. The effect of the different physical non-dimensional flow parameters on different flow profiles such as velocity, temperature, concentration, skin friction, Nusselt and mass transfer rate are depicted through graphs and tables. The velocity profiles diminish with the effect of magnetic and slip parameters. The temperature and concentration slip parameters reduce the temperature and concentration profile respectively. The higher values of magnetic factor lessened the skin friction coefficient for both slip and no-slip conditions. An elevation in the thermal slip parameter reduced the boundary layer thickness and the heat transfer from the surface to the fluid. The Nusselt number amplified with the climbing values of the radiation parameter. The mass transfer rate depressed with the solutal slip parameter. Comparison is made with the published work in the literature and there is excellent agreement between them.
在流体力学领域,由于混合纳米流体对流动和传热特性的影响,其在拉伸表面上的流动已得到广泛研究。通过引入多孔介质来拓展这一概念,当前研究探讨了混合纳米流体的流动、传热和传质特性。该研究包括磁流体动力学(MHD)与化学反应、热辐射及滑移效应的影响。纳米颗粒铜和氧化铝与水混合形成混合纳米流体。利用自相似方法将偏微分方程(PDEs)简化为常微分方程(ODEs)系统。这些非线性方程组采用bvp4c(边值求解器)技术进行数值求解。通过图表展示了不同物理无量纲流动参数对不同流动剖面(如速度、温度、浓度、表面摩擦、努塞尔特数和传质速率)的影响。速度剖面在磁场和滑移参数的作用下减小。温度和浓度滑移参数分别降低了温度和浓度剖面。在有滑移和无滑移条件下,较高的磁因子值都会减小表面摩擦系数。热滑移参数的增加会减小边界层厚度以及从表面到流体的热传递。努塞尔特数随辐射参数值的增加而增大。传质速率随溶质滑移参数而降低。与文献中已发表的工作进行了比较,结果显示两者之间具有良好的一致性。
