Laminar Forced Convection Heat Transfer over Staggered Circular Tube Banks: A CFD Approach

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 volume method (FVM) for the flow ov...
