Abstract
The present study is subjected to heat and mass transfer characteristics of nanofluid flow over different geometries. The nanofluid flow saturated in different solid objects, such as cone, stretching cylinder, Riga plate, channel, stretching surfaces, etc., are commonly used in many
fields of engineering and manufacturing procedures. The involvement of various physical factors, such as magnetic field, thermal radiation, suction/injection, porous medium, slip effects, chemical reaction, heat generation/absorption, Joule heating, viscous dissipation, volume fraction of different nanoparticles (copper and silver), Brownian motion and thermophoresis effects 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 interest, such as skin friction coefficient, Nusselt and Sherwood numbers are studied and discussed in details. The introduction section is filled with the essential notions and definitions related to fluid mechanics. The group of similarity transformations has been utilized to convert the principle equations into non-dimensional set and the Runge-Kutta-Fehlberg method of fourth-fifth order along with shooting technique is used to solve them with the help of computing tools. For validation of present numerical codes, we have compared our results with previously published works. The outcome involving to the related work may be helpful to explore various aspects of nanofluid flow problems over other objects. The obtained results have huge significances in different fields of applied science and different branches of engineering and applied mathematics.
