Abstract

The consequence of periodic body acceleration and thermal radiation in the pulsating flow of MHD Casson nanofluid through a porous channel is addressed. A flow of the nanofluid injected through the lower plate is considered while sucked out through the upper plate with a similar velocity. The thermal radiation term is incorporated in the heat transfer equation. The governing equations corresponding to velocity and temperature are converted from partial differential equations to a system of ordinary differential equations by employing similarity variables. The perturbation technique is applied to solve the governing flow equations. The impact of diverse parameters on flow features is graphically analyzed. The result reveals that adding the nanoparticle has enhanced the velocity profile of the base fluid. Moreover, an increase in the periodic body acceleration results in enlarging velocity and temperature.

Highlights

Introduction e foremost principle ofMHD is that forces are formed by the magnetic field, which stimulates a current through a moving conducting fluid. e importance of MHD in various areas such as astrophysics, biomedical research, and geophysics motivates us to investigate MHD flow
It begins to deform when the yielded stress becomes less significant than shear stress. e MHD flow of Casson fluid in a porous channel is a field of dynamic research due to its applicability in industry and medical technology such as paper production, condensation, and blood flow in the human body
Kumar et al [30] considered the “Joule heating and thermal radiation effects on the pulsatile MHD flow of Casson nanofluid through a vertical porous space.” e study related to periodic body acceleration has enormous applications, analyzing blood flow in the cardiovascular system
