In this analysis we present a theoretical study to examine the combined effect of both slip velocity and periodic body acceleration on an unsteady generalized non-Newtonian blood flow through a stenosed artery with permeable wall A constant transverse magnetic field is applied on the peristaltic flow of blood treating it as an elastico-viscous electrically conducting and incompressible fluid

Figs 6a-6c show the effects of velocity slip variable thermal conductivity and viscosity parameters on the dimensionless velocity temperature and nanoparticle volume fraction (nanoparticle concentration) It is found that the fluid velocity is an increasing function of velocity slip parameter (δ) (see Fig 6a) This is perhaps because when
