| 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 analyzed to determine
enhancement of energy transfer on stretched sheets. In this 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 anddiscussed. 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 values on velocity, temperature and concentration profiles are
discussed. | en_US |
