本文研究了电磁流体动力学边界层纳米流体绕里加板的流动。Darcy-Forchheimer模型被用来描述流体在多孔空间中的运移。本文提出了在化学反应存在的情况下，抽吸和喷射之间的相对流动分析。模型中考虑了布朗运动、热泳和化学反应的影响。我们实现了一个相似性的方法来减少到常微分方程的领先偏微分方程。我们解决由此产生的方程数值使用RK-4射击程序和分析从事高功率微波。通过数值计算，明确了出流参数对流动特性的影响。我们注意到，当孔隙度参数和Forchheimer数增加时，温度和浓度分布是相同的。对于Forchheimer数，热传递在抽吸中富集而在喷射中下降，这推断在通过里加板的纳米流体流的冷却实践中抽吸比喷射更相关。
The electro-magneto-hydrodynamic boundary-layer nanofluid flow over a Riga plate has been examined in the present paper. The Darcy-Forchheimer model is accounted for to characterize fluid transportation in a porous space. A relative flow analysis amongst suction and injection in the presence of a chemical reaction is presented here. Effects of Brownian motion, thermophoresis and chemical reaction are incorporated in the present model. We implement a similarity approach to reduce the leading PDEs into ODEs. We resolve the resulting equations numerically by using the RK-4 shooting procedure and analytically by engaging HPM. After numerical designs, the influence of the emergent flow parameters on the flow specifics are made clear via graphs and charts. We noticed that temperature and concentration profiles are identical when the porosity parameter and the Forchheimer number increase. For the Forchheimer number heat transmission enriches in suction and declines in injection which infers in cooling practice of a nanofluid flow through Riga plate suction is more relevant than injection.
