Abstract: The behavior of the pulsatile flow of Maxwell fluid in a constricted channel is examined. The governing model of the problem is transformed into the vorticity-stream function formulation and numerically solved using a scheme based on the finite difference method. Impact of numerous flow controlling parameters including the Hartmann number, Soret number, porosity number , Renylod number, peclet number, radiation number on the wall shear stress (WSS), axial velocity temperature profile, and concentration are presented graphically and discussed. The WSS is found to increase with rising values of the Hartman parameter. The WSS decreases with rising values of the parameter. The Hartman number is found to have a significant impact on the flow separation region, as well. At the constriction throat, the maximum value of the velocity is identified.
