Abstract

We present a mathematical model and numerical simulation of the unsteady 2-D
g-jitter-free and forced convective flow of water-based nanofluid from a flat plate, considering both
the velocity slip and thermal slip conditions imposed on the wall of the plate. The Darcian model
is used, and both cases of a calm and moving free stream are considered. In place of the extensively
used linearly varying radiative heat flux, the nonlinearly varying heat flux calculation is applied to
produce practically useful results. Further, we incorporate the “zero mass flux boundary
condition” which is believed to be more realistic than the earlier extensively used “actively”
controlled model. The parameter influences on the non-dimensional velocity, temperature,
nanoparticle volume fraction, skin friction and heat transfer rates are visualized graphically and
discussed in detail. Special cases of the results are benchmarked with those existing in the
literature, and a good arrangement is obtained. It is found that the rate of heat transfer is lower for
the calm free stream rather than the moving free stream.
