Abstract |
|
Generally, the notch and un-notched Fin in a plate-fin heat exchanger provides a greater heat transfer coefficient than plain plate-fin, but it also leads to an increase in flow friction. A new parameter, called relative entropy generation distribution factor, is proposed to evaluate the thermodynamic advantages of notch and un-notch fins. This parameter presents a ratio of relative changes of entropy generation. The relative effects of the geometrical parameters are discussed. The results show that there exist the optimum values at a certain flow condition, which obviously maximize the degree of the heat transfer enhancement of notch and un-notch fins |
