Introduction:
Convective heat and mass transfer in nanofluids is a topic of major contemporary
interest in both science and technology. In view of this, an unsteady MHD free convective flow of
nanofluids through a porous medium bound by a moving vertical semi-infinite permeable flat plate with
a constant heat source and convective boundary condition in a rotating frame of reference is studied
theoretically.
Experimental:
The novelty is the consideration of constant heat source and convective boundary condition
in a rotating frame. The velocity along the plate i.e., slip velocity is assumed to oscillate in time
with constant frequency so that the solutions of the boundary layer are of the same oscillatory type. The
dimensionless governing equations for this investigation are solved analytically using small perturbation
approximation. Two types of nanofluids, namely Cu-water and Al2O3-water are used.
Results:
The effects of various parameters on the flow, heat and mass transfer characteristics are discussed
through graphs and tables.
Conclusion:
An increase in the convective parameter and nanoparticle volume fraction leads to increase
the thermal boundary layer thickness but opposite effect occurs for heat generation.
