Impact of chemical reactions that generate and absorb heat in the flow induced by a squeezing porous slider

Physica Scripta, Journal Year: 2024, Volume and Issue: 99(7), P. 075247 - 075247

Published: June 6, 2024

Abstract The three-dimensional flow of a viscous fluid induced by an expanding or contracting porous slider under the influence activation energy with exothermic and endothermic chemical reactions is explored in this study. Moreover, amount injected to levitate changes over time according where it at any instant. With aid similarity variables, modelling equations relating are converted into system ordinary differential equations. Then, solved numerically help Runge–Kutta Fehlberg’s fourth fifth-order method (RKF-45). Graphs used analyze impact various parameters on flow, thermal concentration fields. Results reveal that velocity profiles get smaller as wall dilation parameter rises. An anticipated boundary layer development next results from increased Reynolds number. temperature profile for process has diminishing increases, whereas opposite consequences obtained reaction. For reaction, rises reaction values increase. However, can be seen
