The present research derives analytical expressions
for the heat transfer in a porous annulus with pulsating
pressure gradient imposed across the annulus. The governing
partial and coupled equations are transformed to ordinary
ones by utilizing the similarity variables and then solved
analytically using Homotopy Analysis Method (HAM). The
analytic solution is expressed in the form of series, and its
convergence is analyzed. The resulting temperature distribution,
Nusselt number and entropy generation profiles are
shown graphically for the different values of the parameters
of the problem. A numerical solution has also been obtained
to verify the solution by HAM. Good agreement is observed
between the two methods.
