This study investigates the thermal performance of a fully wet stretching/shrinking longitudinal fin with an exponential profile coated with a mechanism similar to a conveyer belt. The effects of wet parameter, fin shape parameter, and stretching/shrinking parameter on heat transfer and thermal characteristics are analyzed and discussed using graphical methods. It is found that setting a shrinking mechanism on the fin surface can mitigate the negative effects of motion and internal heat generation on heat transfer rate. This research is relevant to practical applications and beneficial for fin design.
The present investigation focuses on the thermal performance of a fully wet stretching/shrinking longitudinal fin of exponential profile coated with a mechanism like a conveyer belt. The modeled equation is non-dimensionalized and solved by applying the Runge-Kutta-Fehlberg (RKF) method. The effects of parameters such as the wet parameter, the fin shape parameter, and the stretching/shrinking parameter on the heat transfer and thermal characteristics of the fin are graphically analyzed and discussed. It is inferred that the negative effects of motion and internal heat generation on the fin heat transfer rate can be lessened by setting a shrinking mechanism on the fin surface. The current examination is inclined towards practical applications and is beneficial to the design of fins.
