摘要：In this study, the thermal performance of moving porous fin wetted with hybrid nanofluid with different cross-sections in the presence of a magnetic field is investigated. As an innovation, three different cross-sections) trapezoidal, concave parabolic and convex (have been used. The Shape-factor effect of hybrid nanoparticles is also considered in the equations. After extracting the governing equations and converting the PDE equations to ODE by Similarity solution, the equations are solved by Akbari-Ganji's method. The boundary conditions are an insulated tip with a finite length, and thermal functions for heat transfer coefficient and conductivity have been assumed. The impacts of several characteristics on the dimensionless temperature are thoroughly investigated, including Peclet number, thermal conductivity parameter, emissivity parameter, heat transfer coefficient parameter, convective–conductive parameter, and radiative–conductive parameter. The results show that Akbari-Ganji's method has good accuracy in solving heat transfer equations related to moving porous fin. Also, increasing the Peclet number increases the dimensionless temperature, because increasing the Peclet number causes the fin to move faster.
