Abstract
In this thesis, an analysis of two and three dimensional laminar convective
boundary layer flow of a nanofluid with microorganism is investigated. It involves two
and three dimensional laminar convective external boundary layer flow with heat and
mass transfer under various physical configurations as well as geometries. The
parameters that involved in this research are consist of magnetic field, heat
generation/absorption, velocity slip, thermal slip, mass slip, microorganisms slip,
viscosity, thermal conductive, mass diffusivity, and microorganism diffusivity.
Melting heat transfer rate, Stefan blowing and multiple boundary conditions are taken
into account. The fluid is characterized to be Newtonian, non- Newtonian, viscous,
incompressible, magnetohydrodynamic and has constant or variable physical
properties. Steady boundary layers are considered and appropriate transformations are
used to transform the partial differential equations into nonlinear ordinary differential
equations. The transformed equations are solved numerically using the bvp4c in
Matlab for various values of the controlling parameters. Graphs are plotted to display
the effect of the controlling parameters on the dimensionless velocity, viscosity,
temperature, concentration (nanoparticle volume fraction), microorganism as well as
skin friction factor, rate of heat, rate of mass transfer and rate of motile microorganism.
The numerical solution for the skin friction factor, rate of heat, rate of mass transfer
and rate of motile microorganism are generated for various values of the parameters.
The flow field and other quantities of physical interest are found to be significantly
influenced by the controlling parameters. A comparison with previously published
work is carried out and the results are found to be in a good agreement.
