Abstract: In this dissertation, the nanofluid flow with the heat and mass transfer for various models of fluids is analyzed. The flows are induced over stretching sheet and two infinite plates. The important quantities such as magneto hydrodynamics, viscous dissipation, Joule heating, chemical reaction, Brownian motion and thermophoresis are incorporated for physical consideration. The MHD Jeffrey nanofluid flow and heat transfer over a stretching sheet considering the Joule heating and viscous dissipation is analyzed. The motion of a non-Newtonian tangent hyperbolic nano fluid past a stretching sheet is also investigated. Further, the effects of chemical reaction, viscous dissipation and Joule heating are also contemplated for the problem. Magnetic field is implemented in vertical direction under the assumption of low magnetic Reynolds number. Moreover, an elaborated evaluation is presented for the stratified MHD Jeffrey nanofluid flow towards a stretching surface in the presence of gyrotactic micro-organisms. And finally the numerical solution of rotating flow of a nanofluid over a stretching surface in the presence of magnetic field. To model the system of partial differential equations, different emerging laws of Physics are used. To convert the system of partial differential equations into the ordinary differential equations, some suitable transformations named as the similarity transformations are utilized. Further, utilizing the Keller box method and shooting technique, the system of ordinary differential equations has been solved with the help of the computational software MATLAB to compute the numerical results. The numerical solution obtained for the velocity, temperature, concentration and density of the motile micro-organisms profiles has been presented through graphs for different choices of the physical parameters. The numerical values of the skin friction, Nusselt, Sherwood and local density number of the motile micro-organisms have also been presented and analyzed through tables. A comparison with the previously available literature in limiting cases is also performed to strengthen the reliability of the code. To further strengthen the reliability of our MATLAB code, the results presented in the previously published articles are reproduced successfully
