The purpose of the study is to scrutinize the entropy generation analysis on magnetohydrodynamic heat transfer flow from Casson single-walled carbon nanotube on a wedge with Joule heating and viscous dissipation. Kerosene oil is considered as base fluid because of its exclusive features, advanced thermal conductivity, application, and unique behavior. Using similarity variables, the regulating equations are modified into nonlinear coupled, ordinary differential equations, which are then tackled using homotopy analysis method. Impacts of emerging parameters on entropy generation, temperature, velocity, and Bejan number distributions are discussed and shown graphically. The Nusselt number and skin-friction coefficient values are shown in a table. The results reveal that velocity enhances due to increasing magnetic and Casson parameters. It was inspected that entropy production enhances due to increasing wedge angle and magnetic parameter and decays with Casson parameter. Also, it is examined that the Bejan number upsurges due to larger Casson and wedge angle

The heat transfer on laminar boundary-layer flow (BLF) of a micropolar non-Newtonian fluid (NNF) due to a wedge with an impact of an aligned magnetic field embedded in a porous stratum accompanied by an effect of velocity and thermal slips are scrutinized. The similarity transformations are utilized to modify the governing partial differential equations into nonlinear, coupled ordinary differential equations. Resultant equations were solved analytically by homotopy analysis method (HAM). The obtained results are shown graphically for angular momentum, velocity, and temperature distributions for emerging parameters like pressure gradient parameter, velocity, and thermal slip parameters, magnetic parameter, porosity parameter, material parameter, angle of inclination, and Prandtl number. The Nusselt number and skin-friction coefficient values are tabulated. It is noticed that extending values of the material variable suppressed the velocity. The impact of an angle of inclination and porosity parameter enhance the velocity profile. A velocity field was suppressed by larger values of velocity slip variable and temperature distribution declined at the surface and it begins to increase for a certain distance with rising values of thermal slip variable. The obtained results are compared with existing results in a limiting case which provides a good agreement.
