Mixed Convective Flow And Heat Transfer Of A Dual Stratified Micropolar Fluid Induced By A Permeable Stretching/Shrinking Sheet

The present study accentuates the magnetohydrodynamics (MHD) flow and heat transfer characteristics of a dual stratified micropolar fluid over a permeable stretching/shrinking sheet. Thermal and solutal buoyancy forces are also included to incorporate with the stratification effect. Similarity, tran...
