ABSTRACT

In this chapter, convection heat transfer inside a square cavity filled with a nanofluid has been analyzed on the basis of new mathematical models, containing the equations of mass, momentum, and heat balance taking into account more realistic empirical correlations for the physical properties of nanofluids (heat capacitance, thermal conductivity, and thermal diffusivity). The used mathematical approaches have been formulated on the basis of Tiwari and Das’ and Buongiorno’s nanofluid models. Numerical simulation using second-order difference schemes allowed to study the effect of governing parameters on streamlines, isotherms, isoconcentrations, and local and average Nusselt and Sherwood numbers. Also future prospects in the analysis of heat transfer inside the porous cavities filled with a nanofluid have been described.
