Impacts of energy transmission properties on non-Newtonian fluid flow in stratified and non-stratified conditions

The flow properties are essential to understanding the mechanism of the working fluid and its effect on energy transmission. This study examines the rheological properties of Williamson fluid flow over an inclined surface when affected by linear stratification and convective surfaces in both thermal and solutal fields. A system of boundary value problems is formulated and addressed by employing similarity variables using a novel iterative method based on the operational matrix technique. The benefit of the numerical method is demonstrated by computing the local truncation error. The computation of the truncation error for some values used to validate the solution. The study examines the impact of various parameters on temperature, concentration, and velocity profiles. The results illustrate that the thermal buoyancy parameter, inclination angle and significantly influence the temperature and concentration distribution profiles, whereas the inertia coefficient has a comparatively minor effect. The analysis presents promising results with the potential for further improvement in future research.
