Abstract

In the present article, peristaltic transport of copper nano fluid in a curved channel with complaint walls is studied. Shape effects of nanosize particles are discussed. The mathematical formulation encompasses momentum and heat conservation equations with appropriate boundary conditions for compliant walls. Sophisticated correlations are employed for thermal conductivity of the nanoparticles. The nonlinear boundary value problem is normalized with appropriate variables and closed-form solutions are derived for stream function, pressure gradient and temperature profile. A detailed study is performed for the influence of various nanoparticle geometries (bricks, cylinders and platelets). With greater curvature value, pressure gradient is enhanced for various nanoparticle geometries. Temperature is dramatically modified with nanoparticle geometry and greater thermal conductivity is achieved with brick shaped nanoparticles in the fluid.
