Abstract.

An analytical investigation is presented to study the unsteady peristaltic transport of nanofluids. Carbon nanotubes analysis is taken into account. The flow geometry is taken as a non-uniform channel of finite length to explore our model for a wide range of biomedical applications. Exact solutions are obtained for the non-dimensional governing equations subject to physically realistic boundary conditions. The effects of carbon nanotubes on effective thermal conductivity, axial velocity, transverse velocity, temperature, and pressure difference distributions along the length of a non-uniform channel with the variation of different flow parameters are discussed with the help of graphical illustrations. An inherent property of peristaltic transport, i.e., trapping is also discussed. We have noticed that MWCnt's have this exceptional quality to increase the axial velocity as well as the transverse velocity of the governing fluids. This model is applicable in drugs delivery system where different geometries of drugs are delivered and it is also applicable to design a microperistaltic pump for transportation of nanofluids.
