A Numerical Study of Forced Convection Heat Transfer for Staggered Tube Banks in Cross-Flow

This paper presents the numerical study on the two-dimensional forced convection heat transfer for staggered tube banks in cross flow under incompressible, steady-state conditions. This system is solved on the body fitted coordinates (BFC) using the finite difference method (FDM)for the flow over a...
