Numerical investigation on activation energy of chemically reactive heat transfer unsteady flow with multiple slips

Abstract

Purpose The purpose of this study is to examine the impact of activation energy with binary chemical reaction for unsteady flow on permeable stretching surface. Design/methodology/approach The simultaneous effects of multiple slip and magneto-hydrodynamic effects at the boundary are taken into account. The thermal buoyancy parameter and thermal radiation are included in both energy and momentum equations, while expression of activation energy is considered in concentration equation. Three-stage Lobatto IIIa finite difference collocation technique with bvp4c MATLAB package is used to obtained numerical results. Findings The influence of key elements (Schmidt number, buoyancy force ratio factor, factor of radiation, magnetic element, unsteadiness factor, suction/injection parameter, Prandtl number, activation energy, chemical reaction rate parameter, heat source and sink parameters, velocity, thermal and concentration slips, porosity parameter and temperature difference parameter) on velocity, temperature and concentration profiles are illustrated pictorially. A detailed discussion is presented to see how the graphical aspects justify the physical prospect. Originality/value In the best of author’s knowledge, this work is yet not available in existing literature.

Numerical investigation of oxygen transport in the retinal artery with higher order accuracy by using seven and nine point finite difference technique: a comparative study

“…The governing equations are manipulated through Method of Lines (MOL) which can covert the PDE into a system of ODEs. Then the resulting system of ODEs are solved efficiently using the Runge-Kutta method of order four (RK4) [21][22][23][24][25][26][27][28][29][30][31][32]. For spatial discretization, the finite difference scheme of 6th (seven-point) and 8th (nine-point) order accurate is employed to solve the PDEs of proposed model but graphs are presented only for 8th order scheme.…”
