In this paper, the heat and mass transfer of MHD nanofluid squeezing flow between two parallel plates are investigated. In squeezing flows, a material is compressed between two parallel plates and then squeezed out radially. The significance of this study is the hydrothermal investigation of MHD nanofluid during squeezing flow. The affecting parameters on the flow and heat transfer are Brownian motion, Thermophoresis parameter, Squeezing parameter and the magnetic field. By applying the proper similarity parameters, the governing equations of the problem are converted to nondimensional forms and are solved analytically using the Homotopy Perturbation Method (HPM) and the Collocation Method (CM). Moreover, the analytical solution is compared with numerical Finite Element Method (FEM) and a good agreement is obtained. The results indicated that increasing the Brownian motion parameter causes an increase in the temperature profile, while an inverse treatment is observed for the concentration profile. Also, it was found that enhancing the thermophoresis parameter results in decreasing the temperature profile and augmenting the concentration profile. Effects of active parameters have been considered for the flow, heat and mass transfer. The results indicated that temperature boundary layer thickness will increases by augmentation of Brownian motion parameter and Thermophoresis parameter, while it decreases by raising the other active parameters.

缩回文章：MHD挤压平行板中纳米流体流动的水热分析方法

本文研究了MHD纳米流体挤压流在两个平行板之间的传热和传质。在挤压流中，材料在两个平行板之间被压缩，然后被径向挤压。这项研究的意义是在挤压流动过程中对MHD纳米流体进行水热研究。影响流动和传热的参数是布朗运动，热泳参数，挤压参数和磁场。通过应用适当的相似性参数，可以将问题的控制方程式转换为无量纲形式，并使用同伦摄动法（HPM）和并置法（CM）进行解析求解。此外，将该解析解与数值有限元方法（FEM）进行了比较，并获得了良好的一致性。结果表明，增加布朗运动参数会导致温度曲线的增加，而对浓度曲线进行反向处理。另外，还发现增强热泳参数会导致温度分布减小和浓度分布增大。对于流动，传热和传质，已经考虑了有效参数的影响。结果表明，温度边界层的厚度将通过布朗运动参数和热泳参数的增加而增加，而通过增加其他活动参数而减小。已经发现，提高热泳参数会降低温度曲线并增加浓度曲线。对于流动，传热和传质，已经考虑了有效参数的影响。结果表明，温度边界层的厚度将通过布朗运动参数和热泳参数的增加而增加，而通过增加其他活动参数而减小。已经发现，提高热泳参数会降低温度曲线并增加浓度曲线。对于流动，传热和传质，已经考虑了有效参数的影响。结果表明，温度边界层的厚度将通过布朗运动参数和热泳参数的增加而增加，而通过增加其他活动参数而减小。
