Abstract
The present study is dedicated to analyze the flow, heat and mass transfer characteristics of nanofluid flow through different geometries under different conditions. The nanofluid flow through different solid objects, such as porous plate, parallel plate channel, bidirectional stretching surface, unidirectional stretching surface, etc., are commonly used in many fields of engineering and manufacturing process. The involvement of various physical factors, such as magnetic field, thermal radiation (linear and non-linear), suction/injection, porous medium, thermophoresis, Brownian motion, heat source/sink (uniform and nonuniform), dissipation, Joule heating, Biot number, volume fraction of nanoparticles and different base fluids in nanofluid flow have been discussed. The influences of these parameters are plotted and discussed to examine the variations in velocity profiles,
temperature and concentration distributions. Moreover, the factors of engineering interests such as skin friction coefficient and Nusselt number are studied and discussed in detail. Response of above-stated factors on entropy generation number and Bejan number are presented graphically and discussed in detail. The introduction section consists of essential notions and definitions related to fluid mechanics. Applying similarity transformations, the principle equations are converted into non-dimensional set further using Runge-Kutta-Fehlberg method along with shooting technique to solve them with the various computing tools. For validation of present numerical codes, results are compared with previously published works. The work presented in this thesis can be useful to explore various expects and dimensions of nanofluid flow problems over other materials. The obtained results are
promising and have significant impact in different field of applied sciences in mathematics and engineering.
