Краткое описание

A numerical study of the effect of viscous dissipation and Joule heating on steady two-dimensional incompressible stagnation point flow of electrically conducting nanofluids along with suction/injection at a stretching/shrinking surface embedded in saturated porous medium and magnetic field is considered. The impact of different types of nanoparticles with base fluid, heat generation/absorption, and thermal radiation are also dealt with. Similarity transformations are applied to reduce the governing partial differential equations into a system of nonlinear ordinary differential equations, which are solved numerically using a Galerkin finite element method. Influences in velocity and temperature distributions due to various nanofluids and appropriate controlling parameters such as mass flux, velocity, solid volume fraction, permeability, magnetization, radiation, heat source/sink, and Eckert number are evaluated through graphs and discussed in detail. Computational values of local skin friction and local Nusselt number against various physical parameters are presented via tables. Moreover, the effectiveness and accuracy of the proposed method are compared with previously published research.
