| Summary: | In this paper, Micropolar liquid flow between two flat plates has been studied in Maple computational software. The innovation of this paper is to study the heat transfer and fluid flow through two parallel plates with Adomian decomposition Method (ADM) and Variation Iteration Method (VIM). Then, the results of these methods are compared with the numerical method under a separate graph. Variation Iteration Method and Adomian decomposition method can be useful for such problems, and the maximum difference in temperature profile and concentration profile is observed between ADM and the NUM method is less than 1 percent. The characteristics of the passing flow, the heat transfer from the fluid to the plates and the surroundings, and the concentration were examined using the Reynolds, angular velocity, and Peclet number parameters. In other words, heat transfer increases with an increase in the Peclet number, and fluid concentration also increases with a rise in the Peclet number. The maximum heat transfer occurs in the ƞ=-1, and the minimum heat transfer occurs in the ƞ=1. In general, by increase the Reynolds number, the amount of stream function decreased.
