Thermal micropolar couple stresses effects on peristaltic flow of biviscosity nanofluid through a porous medium

The main aim of current study is to analyze couple stresses effects on MHD peristaltic transport of a micropolar non-Newtonian nanofluid. The fluid flows through a porous media between co-axial tubes under the effect of radiation, chemical reaction, viscous and Ohmic dissipation. The inner tube is solid and uniform, while the outer tube has an exible wave traveling down its wall. the governing equations have been simplified using low-Reynolds number and long wave-length, then A semi-analytical solutions have been obtained using homotopy perturbation method. Numerical results for the behaviors of the axial velocity, microrotation velocity, temperature and nanoparticles with problem physical parameters are depicted graphically. This study is very significant in diverse medical implementations, as gold nanoparticles are utilized in the remedy of cancer tumor.
