Résumé

In this study, the influences of the changes in fin geometry on heat transfer and pressure drop of a plate fin and tube heat exchanger are investigated, numerically. A computational fluid dynamics program called Fluent is used in the analysis. The results of heat transfer, static, and total pressure drop values of ten different fins are tabulated and the normalized values of them are, also, given for the comparison of the models. Another important result of the study is that increasing ellipticity of the fin tube increases the heat transfer and also results in an important reduction in pressure drop.
