Convective heat transportation in exponentially stratified Casson fluid flow over an inclined sheet with viscous dissipation

Abstract

There are numerous applications related to engineering and industrial manufacturing and processing in which the boundary-driven hydromagnetic flow of non-Newtonian fluids play a vital role. Examples includes glass fiber, electronic devices, paper production, medical equipment, filaments, polymer sheets and medicine. Researchers investigated the heat transportation in fluid flows with linear stratification. However, linear stratification fails when there exists large temperature difference between different bodies. Owing to such facts, here our aim is to explore the features of convective heat model in Casson fluid flow with inclined magnetic field with exponential stratification deformed by linearly stretchable inclined sheet. Characteristics of heat transportations are formulated and investigated through viscous dissipation and heat generation. The reduced non-linear governing expressions are solved analytically by homotopic technique. Analysis of velocity and temperature are comprehensively demonstrated through graphs. Further, rate of heat transfer and drag force are computed graphically via various parameters. It is concluded that inclination and magnetic parameters diminish the flow velocity gradually. Further, temperature field intensifies when Biot number is enlarged while it decays with increasing thermal stratification. It is hoped that the present study will help us to form the homogeneous mixtures of fluids at industrial and biomedical levels especially in food liquids, medical syrups, and medicines.
