Heat and mass transfer of micropolar fluid flow over a stretching sheet by legendre collocation method
Mathematical modeling is more explicitly tied to some physical assumptions as exhibited in Fig. 1. It contemplates a steady, laminar, free convection, and incompressible flow of a micropolar fluid above an expandable sheet \(\:\left(y=0\right)\)…
