Abstract: Nanofl uids are produced by suspending nanometer-sized particles (less than 100 nm) in a pure fl uid such as water, ethylene glycol or propylene glycol. The fi rst to coin the "nanofl uids" for these fl uids with superior thermal properties was Choi (1995). The existence of high thermal conductivity metallic nanoparticles (e.g., copper, aluminum, silver, and titanium) increases the thermal conductivity of such mixtures, thus enhancing their overall heat transfer capability (Xuan et al., 2003). In recent years, nanofl uids have attracted attention as an innovation in using heat transfer fl uids in the MIXED-CONVECTION FLOW IN A LIDDRIVEN SQUARE CAVITY FILLED WITH A NANOFLUID WITH VARIABLE PROPERTIES: EFFECT OF THE NANOPARTICLE DIAMETER AND OF THE POSITION OF A HOT OBSTACLE

Abstract: A numerical simulation for mixed convective three-dimensional slip flow of water-based nanofluids with temperature jump boundary condition is presented. The flow is caused by nonlinear stretching surface. Conservation of energy equation involves the radiation heat flux term. Applied transverse magnetic effect of variable kind is also incorporated. Suitable nonlinear similarity transformations are used to reduce the governing equations into a set of self-similar equations. The subsequent equations are solved numerically by using shooting method. The solutions for the velocity and temperature distributions are computed for several values of flow pertinent parameters. Further, the numerical values for skin-friction coefficients and Nusselt number in respect of different nanoparticles are tabulated. A comparison between our numerical and already existing results has also been made. It is found that the velocity and thermal slip boundary condition showed a significant effect on momentum and thermal boundary layer thickness at the wall. The presence of nanoparticles stabilizes the thermal boundary layer growth.
