Analysis of thermally stratified flow of Sutterby nanofluid with zero mass flux condition

Abstract

In this attempt, we scrutinize the effects of Sutterby nanoliquid flow deformed by a linearly stretchable sheet. Inclined magnetic field is included to explore the features of electrically conducting fluid. Thermal stratification phenomenon is implemented over a horizontal sheet to elaborate the features of heat transfer. Variable fluid feature is also accounted. Zero mass flux condition is incorporated along with Brownian diffusion and thermophoresis phenomenon Using the suitable transformations, the system of partial differential equations are transmuted into coupled system of ordinary differential equations. Approximate analytical solutions are computed via homotopic approach. Graphical behavior of applicable parameters on temperature, velocity, and concentration fields are illustrated and elaborated. Skin friction coefficient and Nusselt number are computed and analyzed. It is found that increase in fluid parameter declines the velocity field whereas temperature field rises for higher thermal conductivity parameter. Heat transfer rate decays for thermal stratification phenomenon. The current attempt is incorporated in diverse processes of industry and engineering including cooling and heating processes in solar water heater, building insulation, electronics, turbines, transportation, power generation, geothermal systems, and engines. Moreover, Sutterby model predicts the characteristics of pseudo-plastic and dilatant fluids. This model is very useful for high polymer solutions and polymer melts which are important industrial materials. Owing by such applications, the present examination has been established.
