Numerical Analysis of Flow and Heat Transfer Characteristics between Two Parallel Plates with Constriction(s)

A numerical study involving graphical analysis has been carried out to investigate fluid flow and heat transfer between two stationary horizontal plates possessing blocks (which restricts flow). Important parameters corresponding to pressure, velocity, temperature, heat transfer coefficient and Nuss...
