TL;DR: In this paper, the hydrodynamic and thermal characteristics of Ag-water nanofluid, filling a differentially heated cubic enclosure, are numerically investigated using a developed computer code based on the lattice Boltzmann approach coupled with the finite-difference method.

TL;DR: In this article, a numerical study of mixed convection in a square enclosure, filled with a mixture of water and different types of nanoparticles, was performed. And the results showed that the mean Nusselt number is an increasing function of the decrease Richardson number, and increases with increasing values of the nanoparticles volume fraction.

TL;DR: In this article, the authors used the finite volume method and the SIMPLER algorithm to solve the Brinkman extension of the classical Darcy equation for the momentum conservation equation.

TL;DR: In this article, the impact of some pertinent parameters, such as Lewis and solutal Rayleigh numbers as well as the buoyancy and the aspect ratios, on a viscoplastic materials' double-diffusive convection which occurs within an SiC annulus, contained between a cold and less concentric outer circular cylinder and a hot "and concentric" inner one, to come out with innovative correlations what predict the mean transfer rates into such annulus.

TL;DR: In this article, a mixed convection heat transfer, taking place within a ventilated cubic cavity crossed by an alumina-water nanofluid, is considered, and the results are presented in the form of streamlines, isotherms, velocity vectors and average Nusselt number.
