Studying peristaltic transport of shape nanosize silver-water nanomaterials in digestive system with heat generation effect

This communication addresses the peristaltic transport of silver water nanofluid in the curved channel. Shape effects of nanosize particles are examined. Bricks, cylinder and platelets types nanoparticles are considered. Magnetic field is applied in the radial direction. Viscous dissipation and heat generation in the energy expression are included. Velocity and thermal slip conditions are invoked. Thermal conductivity model due to Hamilton-crosser is employed. A comparative study of velocity and the temperature for the considered nanoparticles is made. Outcome of sundry variables on velocity and temperature are graphically examined. It is noticed that both velocity and temperature are greater for brick type nanoparticles in comparison to cylinder and platelets. Moreover, the velocity is not symmetric about center of channel.
