Abstract


The effect of heat generation/absorption on the peristaltic flow of a Jeffrey fluid with suspended nanoparticles through an asymmetric channel, having flexible walls is considered.  General boundary conditions on velocity, temperature and concentration of nanoparticles are considered. The contribution of nanoparticles to heat and mass transports are modeled by thermophoresis and Brownian diffusion effects.  The governing equations of motion reduce to a system of partial differential equations under long wave length approximation and low Reynolds number limit.  Closed form solutions of the resultant partial differential equations are presented for velocity, temperature and nanoparticle concentration distributions. Effects of various physical parameters like, Jeffrey fluid parameters, slip parameter, Biot numbers, thermophoresis parameter, Brownian motion parameters and heat source/sink parameter on velocity, temperature, nanoparticle concentration and pressure rise over a wavelength are discussed. The results of the paper may lead to possible technological applications in the field of biomedicine.
