Adomian Decomposition Method for the Radiative Micropolar Nanofluid Past a Porous Channel: An Analytical Approach

Abstract

Present analysis leads to investigate the flow of conducting micropolar nanoliquid past a porous channel. The transverse magnetic field is imposed in the normal direction of the flow. The energy equation is enhanced by adopting the influence of thermal radiation. Similarity variable augmented with stream function is used to renovate PDES to ODEs. The present article's special desirability is the approximate analytical technique for these transformed governing equations. We have employed Adomian Decomposition Method (ADM). Descriptions of various profiles for the influence of different parameters are presented through graphs. However, the computation for the rate coefficients is also obtained and deliberated through the tabular form for the influence of diverse physical parameters. A significant contribution reveals that near the lower wall, heat transfer rate enhances greater thermal radiation while impact opposes at the upper wall. A comparison between the methodology newly adopted and the earlier solutions coincided with each other and was found to be in good agreement in particular cases. However, the major findings are laid down here as higher magnetic number favors enhancing angular velocity within the channel and fluid temperature increases due to an increase in thermophoresis parameter.
