摘要

Investigation of nanofluids under microbial movement is a potential topic from applications point of view. This study focuses on the analysis of hybrid nanomaterial based microorganism model between finite boundaries. These boundaries consist of two walls having expansion or contraction property. Formulation of the problem comprises governing laws representing the flow of microorganism in the presence of physical effects and hybrid nanofluid effective characteristics. Similarity functions are adopted for conversion of the primary model into final form and then studied through Variational Iteration scheme. Successful implementation of the scheme provided considerable convergence and better results for the model with fluctuating physical parameters. It is found that increasing permeation and magnetic field significantly controlled the velocity in the channel. Presence of heat generation influentially enhances the temperature for both expansion and contraction cases; while the Soret effects help to augment the density motile of microorganism. The shear drag varies from 0.9057 to 1.1458 ( \(\:{\phi\:}_{1}\) ), 0.9076 to 0.2470 ( \(\:S\) ) in contraction case at the lower surface. This magnitude changes from 0.6762 to 0.6774 ( \(\:{\phi\:}_{1}\) ), 0.6793 to 0.1558 ( \(\:S\) ) at upper expanding surface. Contracting of the walls promoting this factor from 1.9017 to 1.8970 and 1.3982 to 1.3964, for \(\:{\phi\:}_{1}\) and \(\:S\) , respectively. Further, the expanding walls heat transfer rate improves from 0.0509 to 0.0568, 1.4957 to 1.4981 and it depreciates from 0.0480 to 0.0461, and 1.4922 to 1.4839 in contracting walls.
