This research investigates the heat and mass transfer of a micropolar electrically conducting fluid between two stretchable disks, using the Homotopy Perturbation Method to solve nonlinear ordinary differential equations. The study discusses the influence of various parameters on fluid properties and compares the outcomes with previously published work, demonstrating the correctness and accuracy of the analytical method. Results including skin friction coefficient, couple stress, and rates of heat and mass transfer are presented and compared with literature, with numerical computations conducted using the Maple software package.
In this research, the simultaneous effect of heat and mass transfer of a micropolar electrically conducting fluid which is confined between two stretchable disks is studied analytically. The obtained higher-order nonlinear partial differential equations are reduced into a set of nonlinear ordinary differential equations after using suitable similarity transformation. A well-recognized analytical method named Homotopy Perturbation Method is employed to solve nonlinear ordinary differential equations. The influence of Reynolds number, magnetic field, Eckert number, Prandtl number, Radiation parameter, and Schmidt number on velocity, microrotation, temperature, and concentration profiles are discussed and presented graphically. A comparison between outcomes obtained by the homotopy perturbation method (HPM) and the results of previously published work show the correctness and accuracy of the analytical method HPM. The coefficient of skin friction, couple stress, rate of heat, and mass transfer are also tabulated and compared with literature. The Maple software package is used for numerical computation.
