ABSTRACT

The theme of current research is to explore the impact of entropy generation on mixed convective flow of micropolar fluid containing water-based TiO2 nanomaterial toward a vertical surface in a non-Darcy porous medium. The results are confined for opposing and assisting flows. Similarity equations are achieved and then worked out numerically by the Keller box technique. The impacts of substantial parameters on temperature distribution, velocity profile, and microrotation velocity, together with the Nusselt number and the skin friction, are illustrated with the help of graphs. Two solutions are achieved in opposing flow while the solution is unique in assisting flow. It is also observed that the separation of boundary layer accelerates due to volume fraction and delays due to micropolar parameter.
