Numerical solution of heat and mass transfer using buongionro nanofluid model through a porous stretching sheet impact of variable magnetic, heat source, and temperature conductivity.

Abstract

Fluid flow chronologically is widely recognized due to its various uses in turbines, the framework of spinning magnet stars, gyromagnetic generators, and chemical engineers observing the progression of petroleum through the aquifer, and blood vessels in the respiratory alveolar plate. Tropical cyclones, pools of water, and storms all exhibit rotational movement. The current investigation aims to analyse the micro polar fluid flow between two infinite vertical discs enclosing Hall impact, varying thermal conductivity, heat flux as well as anomalous heat generation. The implication of a chemical change combined with chemical potential improves mass propagation. Suitable similarity conversions are used to convert the defined problems into conventional differential equations (ODEs). Furthermore, by introducing new variables the ODEs are transformed into nonlinear coupled ODEs and then solved numerically by the RK 4th order along with the shooting technique. The velocity profiles decrease as suction parameter increases. The temperature field exhibits a rising behaviour for the increasing values of thermophoresis, Brownian and radiations parameters while the concentration field shows a decreasing behaviour. Shear stress at the upper wall increases when the rotation variable and suction variable are augmented. Heat transmission escalations at the bottom wall when Prandtl number and radiation factor are enhanced. The novelty of the present work is to examine the Buongionro model in the presence of a heat source and chemical reaction inside the Darcian porous rotating channel, which has not been investigated yet. In some limiting cases, a comparison of the on-going study with existing literature is also included to justify the contemplated problem.
