摘要

In the present investigation, an analytical analysis has been carried out to study the flow and heat transfer characteristics of nanofluid in an expanding or contracting porous pipe. Blood is considered as base fluid and gold (Au) as nanoparticles are added to the base fluid. Similarity transformations have been invoked to reduce the governing flow equations into coupled nonlinear ordinary differential equations. An analytical approach, namely the homotopy analysis method (HAM) is employed to obtain the analytical solutions for the coupled non-linear system of equations. The effects of various physical parameters on temperature and heat transfer rate of nanofluid have been discussed in detail.
