摘      要：The present paper explains the temperature attribute of a convective-radiative rectangular profiled annular fin with the impact of magnetic *** effect of thermal radiation,convection,and magnetic field on thermal stress distribution is also studied in this *** governing energy equation representing the steady-state heat conduction,convection,and radiation process is transformed into its dimensionless nonlinear ordinary differential equation(ODE)with corresponding boundary conditions using non-dimensional *** obtained ODE is then solved analytically by employing the Pade approximant-differential transform method(DTM)and modified residual power series method(MRPSM).Moreover,the important characteristics of the temperature field,the thermal stress,and the impact of some nondimensional parameters are inspected graphically,and a physical explanation is provided to aid in *** significant findings of the investigation reveal that temperature distribution enhances with an increase in the magnitude of the heat generation parameter and thermal conductivity parameter,but it gradually decreases with an increment of convectiveconductive parameter,Hartmann number,and radiative-conductive *** thermal stress distribution of the fin varies considerably in the applied magnetic field effect.
