Effect of Heat Source on MHD Flow Through Permeable Structure under Chemical Reaction and Oscillatory Suction

Abstract

Magnetohydrodynamics (MHD) deals with the study of the magnetic properties and behaviour of electrically conducting fluids. In literature, researchers have studied. The study of MHD is widely applied in drawing of plastics and elastic sheets, metal and polymer expulsion forms, paper creation, cooling of metallic sheets, etc. Most of the previous researchers have studied only the concentration and velocity boundary layer profiles. However, the effect of heat sources using temperature boundary layer profiles is not studied. Therefore, in this work, an analysis of a convective flow of an electrically conductive, viscid compact fluid through a perpendicular plate which is porous with oscillatory suction with first-order temperature and chemical reaction and the transverse magnetic field is carried out. The developed model consists of continuity, momentum, and heat and mass transfer equations, and the perturbation technique was applied in order to find the result for the velocity field, temperature profiles, and concentration distributions. Further, the influence of the flow variables on the temperature field, velocity field, and concentration dispersal was analyzed and the results were depicted graphically. Moreover, the skin friction and the rate of mass transfer (local Sherwood number) were analyzed using tables. In this work, an unstable 2D flow of a laminar, viscid (Newtonian), electrically conducting fluid across a semi-limitless perpendicular permeable plate under motion in its plane (x-axis) embedded in a constant permeable structure was investigated.
