Performance analysis of diffusive thermo and thermo diffusive aspect in rate type chemically reactive liquid subject to variable fluid properties

Abstract

The analysis of chemically reactive rheological liquids subjected to heat-mass transference has turn out to be more and more influential in chemical engineering, drawing considerable relevance. Such rising relevance is noticeable in diverse utilizations, for illustration food processing techniques, scattering and formation of haze, damage of crop via freezing temperatures, cooling towers and the distribution of moisture together with temperature in both orchards and agricultural fields. This study accounts chemically reactive diffusive-thermo and thermo-diffusive flow of Oldroyd-B material induced by vertically moving surface. Modeling of thermal (energy) and species concentration is based on thermal source, variable conductivity, chemical reaction and variable diffusivity. The non-dimensionalized steady-state model for boundary-layer stretchy flow is obtained by deploying similarity transformations and then built-in maple software based on shooting scheme is implemented for nonlinear computational analysis. Results graphically and arithmetically depict dimensionalized profiles providing realistic insights for engineering utilizations. It is inspected that both thermal and solutal fields increase when varying conductivity and varying diffusivity factors are boosted. Besides, it is noticed that absolute percentage increase for Pr is 17.75 % from 1.3 to 1.1 while a decay of 35 % is observed in Df from 0.2 to 0.1.
