Role of Variable Liquid Properties in 3D Flow of Maxwell Nanofluid Over Convectively Heated Surface: Optimal Solutions

摘要

In the present investigation, the variable liquid properties of three-dimensional hydromagnetic Maxwell nanofluid over bidirectional convected heated surface have been considered. The upper convected Maxwell (UCM) liquid model is used to characterize the non-Newtonian nature. The concept of the boundary-layer theory is implemented for the mathematical analysis of the physical phenomenon. Dimensionless variables are considered to change the partial differential system into ordinary ones. The optimal homotopic scheme is proposed for the development of analytical solutions. The importance of involved physical constraints namely liquid viscosity and magnetic parameters, Biot number, Deborah numbers, parameter of Brownian movement, Prandtl number, parameter of thermophoretic and Lewis number on liquid velocity, temperature and concentration is elaborated graphically and numerically. The analysis reveals that the influence of Biot number and Deborah numbers on temperature gradient is quite opposite.
