Abstract
Fluid flow and heat transfer in a plate-fin and tube heat exchange were studied, using a fundamental model consisting of a pair of parallel plates and a square cylinder passing perpendicularly through the plates, which simulated plate-fins and a tube, respectively. The analytical results were reported for a laminar flow at Reynolds number Re=200 in the present paper. Complicated aspects of the fluid flow were shown in terms of velocity vectors, path lines, pressure contours, wall shear stress distributions and separation lines, and the flow mechanism was investigated in detail. In addition, the possibility of realization of an unsteady flow was examined.Keywords
