| dc.description.abstract | Many heat transfer processes in engineering problems in areas such as nuclear reactors and
electronics, as well as in biomedicine and food industry require the knowledge of nanofluids,
consequently investigations leading to understanding of the role played by nanofluids in heat
transfer enhancement in these processes is vital. Currently, numerous studies are being conducted
on nanofluids for the benefits associated with low energy costs and less negative environmental
impact in industry and society. In the studies, water is commonly used as base for nanofluids in
heat transfer applications due to its ability and availability for heat transport. In most of these
investigations influence of nanoparticles have been analysed to determine enhancement of energy
transfer on stretched sheets. In our research, magnetohydrodynamic mixed convection flow of a
nanofluid over a stretching sheet with water equally as the base fluid and either Copper or Silver
as nanoparticles is examined and analyzed. The physical problem is modeled using systems of
unsteady nonlinear differential equations (DE) subject to prescribed boundary and initial
conditions, which are then studied using Finite volume approach. These DE comprise of the
classical continuity, momentum, concentration and energy equations, which are subsequently non
dimensionalized and discretized in rectangular domain. The effect of nanoparticle volume fraction,
Hartmann number, suction and stretching parameter values on and characteristics of velocity, temperature and concentration profiles, and skin friction, heat transfer, and mass transfer
coefficients are discussed. | en_US |
