Awais, “ Numerical study of heat and mass transfer in MHD flow of nanofluid in a porous medium with Soret and Dufour effects,” Heat Transfer (published online, 2021). A new framework of heat and mass transfer with the involvement of thermal diffusion and a heat generation porous medium in nanofluidics was excellently disclosed by Qureshi 5 5. where he shows his concern to investigate the solar radiation influence on 2D stagnation point nanofluidics flow with the help of the differential quadrature method (DQM) technique. Hatami, “ Solar radiation effects on MHD stagnation point flow and heat transfer of a nanofluid over a stretching sheet,” Case Stud. One of the applications of the stretching sheet can be found in the studies recently carried out by Ghasemi 4 4. They found that the temperature profile significantly increased by raising the chemical reaction, heat source, and suction parameter. showed an exertion to study the MHD effects with the transfer of heat in Casson nanofluidics and along with convective end conditions. Bilal, “ MHD Casson nanofluid flow over nonlinearly heated porous medium in presence of extending surface effect with suction/injection,” Indian J. used the Chebyshev pseudo-spectral method to analyze the study of MHD stagnant point flow analysis and exchange of heat through a stretching layer with the existing thermal source. Sibanda, “ A new numerical approach to MHD stagnation point flow and heat transfer towards a stretching sheet,” Ain Shams Eng. tested and analyzed several measurements on the MHD flux across a thermal stretching sheet. Tlili, “ MHD flow and heat transfer over vertical stretching sheet with heat sink or source effect,” Symmetry 11(3), 297 (2019). Stagnant point flow measurements leading to a stretching surface contain multiple uses in both chemical and industrial sectors, including aerodynamic extrusion, fiberglass processing, and cooling and bleaching of tissues. First of all, Hiemenz discussed stagnation point flow in 1911, where he developed an exact solution, while Homann (1936) analyzed the axisymmetric case. Qualitative study analysis has a significant impact on a variety of industrial applications such as plastic film drawing, the boundary layer in the processing phase of the liquid film, and plastic sheet aerodynamic extrusion. Because of various applications in engineering science, the analysis of magneto-hydrodynamics (MHD) and heat distribution of viscous material across a stretching layer is of great significance. The velocity of the fluid flow was initially considered to be an increasing function of heat generation, buoyancy parameter, and magnetic field strength, but it later revealed as a decreasing function of the Prandtl number.įluid movements and heat exchange assessment across a stretching surface is an interesting topic for many researchers working in the stagnant point flow region sector. Upon verifying the homology of the current study with some past investigations, a good harmony is revealed.

Some physical effects reveal that an increase in the Hartmann number raises the fluid’s boundary layer that shows the reverse phenomena of Lorentz force because the speed of the free stream transcends the stretching surface. Furthermore, flow and heat transfer effects for different physical parameters such as the stretching parameter, mixed convection parameter, magnetic parameter, heat generation coefficient, and Prandtl number are analyzed. Results are measured numerically and plotted graphically for velocity and temperature distribution.
The transformed scheme is mathematically resolved by the homotopy analysis method. The classifying boundary layer equations are converted to a set of non-linear equations by taking advantage of similarity structures. The objective of this work is to analyze the impact of magneto-hydrodynamics flow across a stretching layer in the existing magnetic sector.
