This study built up a numerical scheme of using a compound grid system around solid bodies for the purpose of predicting the heat transfer characteristics of actual fin and tube heat exchangers. The scheme was validated by comparing the present numerical results with the experimental ones by Eckert and was confirmed to be quite effective in the simulation of the complicated cases such as in-line cylinder arrays and offset cylinder arrays as well as inclined fin arrays, which are basic units of fin and tube heat exchangers. As secondary results, it was found that, for in-line cylinder arrays, the ake length of the cylinders is an important parameter affecting the instability of wake flow, and for offset cylinder arrays, the smaller cylinder row pitch slightly increases heat transfer but obviously leads to larger pressure loss.
