Nanofluid Flow using Buongiorno Model over a Stretching Sheet and Thermophysical Properties of Nanoliquids


The nanofluid flow using Buongiorno model over a stretching sheet and thermophysical properties of nanoliquids is numerically studied. The transformation of the governing partial differential equations into nonlinear ordinary differential equations is done using the similarity variables. Therefore, it has been solved numerically using shooting technique. Four nanoparticles (water based fluid) are considered in this study, namely silver Ag, copper Cu, aluminium oxide or known as alumina Al2 O3 and lastly titanium oxide or known as titania TiO2 . The numerical results obtained are the velocity profile, temperature profile, and nanoparticle concentration profile. Besides, the results of the local Nusselt number and local Sherwood number are also found. These results are then displayed graphically and argued. The flow and heat transfer performance is discussed in the presence of thermophoresis Nt and Brownian motion Nb and nanoparticle volume fraction φ. This study has shown that the stretching sheet is an unique solutions. Otherwise, when φ increases, Nb decreases and Nt decreases, the heat transfer rate increases.
