Numerical solution of EMHD GO-MoS₂/H₂O flow and heat transportation toward stretching/ shrinking riga plate with joule heating and convective boundary condition

This research includes a convective boundary condition and joule heating in a numerical study of the EMHD stagnation point flow of a GO-MoS₂/water hybrid nanotluid across a contracting sheet. The governing partial differential equations are transformed using a similarity criterion into non-linear ordinary differential equations of third and second order. 'I'he bvp4c solver is then used to perform the numerical solution of these equations. Graphs and discussions of the computational results for the skin friction coefficient. local Nusselt number, velocity. and temperature profiles for a range of physical parameter values are provided. Dual solutions provide intriguing behaviour for specific governing factors. According to the findings, the magnetic field parameter. Eckert number and the radiation parameter all have a role in determining the velocity and the temperature. Significant changes occur in the local Nusselt number and skin friction coefTicient when suction is present. It is noted that the performance of skin friction is enhanced with the Hartmann number and suction parameter, while the radiation and Biot numbers can improve the heat transfer rate.
