چکیده
In the present study, the thermal performance of a moving trapezoidal heat fin featuring temperature-dependent thermophysical properties has been evaluated. The governing equation for the temperature distribution of the fin was formulated for two cases: linear and nonlinear thermal conductivity. The governing equation, being a nonlinear ordinary differential equation (ODE), was solved using the Homotopy Perturbation Method (HPM). The results obtained from HPM show good agreement with numerical results from previous studies. Finally, the effects of design and physical parameters on the dimensionless temperature distribution and fin efficiency were investigated. It was found that increasing the fin taper ratio, convection-conduction parameter, temperature ratio parameter, and radiation-conduction parameter leads to a decrease in the dimensionless temperature of the fin. Conversely, increasing the Péclet number and heat source parameter results in an increase in the dimensionless temperature. Moreover, increasing the aforementioned parameters leads to a reduction in fin efficiency. The dimensionless temperature and fin efficiency for the case of linear thermal conductivity are higher than those for nonlinear thermal conductivity.
