Abstract

• The Newtonian heating on heat transport on MHD flow of Casson fluid are explored. • The PDE for governing the flow are solved by using Laplace transform method. • The velocity, temperature, and species concentration are portrayed graphically. • The skin-friction, Nusselt number,and Sherwood number are represented in tables. • The problem has lot of applications and in hydrology and purification of crude oil. In the current paper, the impacts of the Newtonian heating on the heat and mass transportation in unsteady MHD flow of the Casson fluid past a vertical plate by means of temperature radiation and chemical reaction are investigated with Hall and ion slip effects. The Casson fluid model is utilizing to distinctive the non-Newtonian fluid performance. The fluid flow is convinced suitable to periodic oscillations with the plate next to this length and the uniform transverse magnetic field is abounding to the direction, it is perpendicular to the direction of the fluid movement. The partial differential equations for the governing flow momentum, temperature, and mass transportation are converted into a non-dimensional form using the appropriated non-dimensional variables. Then these are later solved systematically with Laplace transformation technique. The current computational quantities namely, the fluid velocity, temperature, and species concentration are portraying with graphical profiles. In addition, the skin-friction, Nusselts number, in addition Sherwood number are presented in the tabular format with respect to the non-dimensional parameters. Therefore, it is noticed that, the fluid velocity and the temperature are reducing with growing in Casson parameter while the concentration field is reducing with an increased in chemical reacting parameter along with Schmidt number. Therefore, the fluid flow model has quite the lot of engineering and medicinal applications these are, in glass manufactures, paper production, and purification of crude oils and investigation of the blood movement in the cardio-vascular systems.
