The nanofluid flow saturated in different solid objects, such as stretching sheet, stretching cylinder, Riga plate, rotating disc, etc., are commonly used in many fields of engineering and manufacturing procedures. Numerous physical phenomena are involved in the various flow conditions, including the magnetic effect, velocity slip effect, thermal slip effect, suction/injection, Brownian motion and thermophoresis effects, porosity, heat generation/absorption, thermal radiation, Arrhenius energy, chemical reaction, viscous dissipation, Joule heating, and nanoparticle volume fraction, in nanofluid flow have been discussed. To investigate the variations in velocity profiles, temperature, and concentration distributions, the influences of these parameters are plotted and discussed. Moreover, the factors of engineering interest, such as skin friction coefficient, Nusselt and Sherwood numbers are studied and discussed in details. The system of governing non-linear partial differential equations is transformed into the system of coupled non-linear ordinary differential equations by applying an appropriate transformation. Then, the Runge-Kutta-Fehlberg method of fourth-fifth order along with shooting technique is used to solve them with the help of computing tools. Also, bvp4c, bvp5c MATLAB inbuilt solver are used. For validation of present numerical codes, the result are compared with previously published works. Thus, an excellent correlation between the current results and the available solutions in the literature is attained. The obtained results have huge significances in different fields of applied science and different branches of engineering and applied mathematics.EnglishThesis
