A Group Theoretic Analysis of Mutual Interactions of Heat and Mass Transfer in a Thermally Slip Semi-Infinite Domain

Abstract

Group theoretic analysis is performed to get a new Lie group of transformations for non-linear differential systems constructed against mass and heat transfer in the thermally magnetized non-Newtonian fluid flow towards a heated stretched porous surface. The energy equation is used with additional effects, namely heat sink and heat source. The chemical reaction is also considered by the use of the concentration equation. The symmetry analysis helps us in numerical computations of surface quantities for (i) permeable and non-permeable surfaces, (ii) thermal slip and non-thermal slip flows, (iii) magnetized and non-magnetized flows, (iv) chemically reactive and non-reactive flows. For all these cases, the concerned emerging partial differential system is transformed into a reduced ordinary differential system and later solved numerically by using the shooting method along with the Runge-Kutta scheme. The observations are debated graphically, and numerical values are reported in tabular forms. It is noticed that the heat transfer rate increases for both the thermal slip and non-slip cases. The skin friction coefficient declines towards the Weissenberg number in the magnetized field.

Dynamics of Triple Diffusive Free Convective MHD Fluid Flow: Lie Group Transformation

“…Using nanofluid, Uddin et al [15] utilized this transformation to analyze the boundary layer in MHD fluid flow on a stretched surface. MHD heat transfer in thermal slip using a semi-infinite domain and Carreau fluid was discussed by Rehman et al [16]. Using this transformation, many researchers gave exact solutions to their problems [17,18].…”

MHD flow of the novel quadruple hybrid nanofluid model in a stenosis artery with porous walls and thermal radiation: A Sisko model‐based analysis

“…Many researchers have extensively investigated the theoretical aspects related to the flow of non-Newtonian blood in narrowed arteries, as indicated by several studies [63][64][65][66][67]. The latest significant findings regarding the flow of non-Newtonian substances in various configurations can be explored in the references [68][69][70][71][72].The Sisko model was first proposed by Malik et al [73]. Since then, the Sisko model has been used in a number of studies to investigate the flow of blood through stenosis arteries.…”

Numerical Simulation of Heat and Mass Transfer in Sludge Low-Temperature Drying Process

“…Sludge drying is a complex heat and moisture transfer process. In terms of heat and mass transfer research, Khalil UrRehman [ 9 , 10 , 11 ] noticed that in non-porous and porous media, t Nusselt number has a direct relationship with the change of Prandtl number for the mathematical model of heat transfer in Carreau fluid flow with physical effects and the corresponding solutions. At the same time, they also used group theory analysis, human intelligence, and other methods to study heat and mass transfer problems.…”
