Heat and Mass Transfer Analysis in Chemically Reacting Flow of Non-Newtonian Liquid with Local Thermal Non-Equilibrium Conditions: A Comparative Study

Abstract

In the current paper, we endeavour to execute a numerical analysis in connection with the boundary layer flow induced in a non-Newtonian liquid by a stretching sheet with heat and mass transfer. The effects of chemical reactions and local thermal non-equilibrium (LTNE) conditions are considered in the modelling. The LTNE model is based on energy equations, and provides unique heat transfer for both liquid phases. As a result, different temperature profiles for both the fluid and solid phases are used in this work. The model equation system is reduced by means of appropriate similarity transformations, which are then numerically solved by employing the classical Runge–Kutta (RK) scheme along with the shooting method. The resultant findings are graphed to show the effects of various physical factors on the involved distributions. Outcomes reveal that Jeffrey fluid shows improved velocity for lower values of porosity when compared to Oldroyd-B fluid. However, for higher values of porosity, the velocity of the Jeffery fluid declines faster than that of the Oldroyd-B fluid. Jeffery liquid shows improved fluid phase mass transfer, and decays more slowly than Oldroyd-B liquid for higher values of chemical reaction rate parameter.

“…Venkatadri et al 35 scrutinized the constant viscous melting transformation of heat in magnetohydrodynamic pressured driven MHD nanoliquid with radiative thermal flux and predict the physical ranges for better heat transmission. Alhadhrami et al 36 endeavored to carry out a numerical analysis in relation to a boundary layer, 37 use a stretching sheet with heat/mass transfer and the flow of non-Newtonian liquid. The consequences of chemical reactions and nearby thermal non-equilibrium (LTNE) prerequisites are regarded in the modeling.…”
