The entropy generation analysis of a reactive hydromagnetic couple stress fluid flow through a saturated porous channel

This study investigates the analysis of a reactive hydromagnetic fluid flow of a couple stress fluid through a saturated channel with porous materials. The analytical expressions for the fluid motion and heat transfer are obtained to find the rate of entropy generation with the use of modified Adomian decomposition method (mADM) as well as determining the critical values. The results are compared with previously obtained results to validate the use of mADM. Also, the impact of magnetic strength and other thermophysical parameters are presented and discussed in tables and graphs to show the impact of magnetic strength on fluid motion, heat transfer and rate of entropy generation.
