The paper deals with a theoretical investigation of the peristaltic transport of a couple-stress fluid with heat and mass transfer effects. The velocity, pressure drop, time averaged flux, frictional force, mechanical efficiency, temperature profile, nano particle phenomena, heat transfer coefficient and mass transfer coefficient of the fluid are investigated, when the Reynolds number is small and wave length is large by using appropriate analytical methods. Effects of different physical parameters like couple-stress fluid parameters, Brownian motion parameter, thermophoresis parameter, local temperature Grashof number as well as local nano particle Grashof number on pressure drop characteristics, frictional force, heat transfer coefficient, mass transfer coefficient and steam line patterns of the fluid are studied.The expressions for velocity, temperature profile, nano particle phenomenon, heat transfer coefficient and mass transfer coefficients are sketched through graphs. The streamlines are drawn to discuss trapping phenomenon for some physical quantities.
