Abstract


The present work deals with the flow and thermal analysis of nanofluid in the wavy channels.  The governing flow equations are solved numerically using CFD package assuming single phase approach.  To study the effect of the concentration and size variation of the nanoparticle, the concentration and size are varied from 0% - 5% and 25 nm - 100 nm respectively over the Reynolds number range of 250-1500 for Au-water nanofluid.  The effect on heat transfer enhancement because of corrugation of wavy channel is analyzed on four different shapes (sinusoidal, triangular, trapezoidal and square) channels.  The effect of amplitude of the wavy channel is analyzed by varying it from 1 mm-3 mm over the considered Reynolds number range.  Also the effect of phase difference between the top and bottom wavy walls is investigated and its effect on the thermal and flow parameters are reported.
