The study of Cattaneo–Christov heat and mass fluxes and stratifications concept in Carreau fluid with variable mass diffusivity

Abstract

Recently, the scientists have been giving attention to the mutual pattern of heat and mass transportation such that both phenomena endorsed the novelty in engineering and industrial equipment’s approximating polymer progressions, fridge-freezers, plastics extrusion, fissile vessels, irrigation of arithmetical kit and power generation, heat exchangers. The Fourier and Fick laws are exploited to describe exactly how the heat and mass transportation via a space with influence of temperature and concentration will change, respectively. Furthermore, the worth of thermo-solutal transport has increased extremely in numerous industrial and scientific progresses, for instance, nutrition processing, utensils power aerials, crop mutilation, thermal transmission in fleshy tissue and numerous others. The theme of this effort is to explore the theory of thermo-solutal relaxation times (Cattaneo–Christov double diffusion) and thermo-solutal stratifications in Carreau fluid with the properties of magnetic field. Additionally, the thermal phenomenon of variable conductivity and mechanism of solutal diffusivity had been studied. The bvp4c algorithm has been exploited for the solution process. It is remarkable to note that both velocity fields decay for magnetic factors. The higher estimations of variable conductivity and thermal stratification factors have contradicting performance on temperature field. Additionally, mass stratification depreciates the concentration of Carreau fluid. The coefficient of skin frictions is enhanced for magnetic factor. The comparative tables compared with past studies with worthy settlement have also been shown.
