RETRACTED ARTICLE: Hydrothermal analysis on MHD squeezing nanofluid flow in parallel plates by analytical method

Abstract

Background: 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. Methods: 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. Results: 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. Conclusions: 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.

“…Thermal analysis of biological systems is a vibrant area of modern biomechanics and biomedical engineering. Thermal science deals with properties of the substances associated with pressure, density, velocity, viscosity, and temperature and their relationship with energy which can be studied from the literature . Thermal science is divided into biological thermodynamics, classical thermodynamics, equilibrium and nonequilibrium thermodynamics, statistical thermodynamics, and heat transfer.…”
