Effects of two-phase nanofluid model and localized heat source/sink on natural convection in a square cavity with a solid circular cylinder
TL;DR: In this paper, the authors investigated the effect of the Rayleigh number on the thermal conductivity of a solid cylinder in a cavity with a solid circular cylinder and found that the heat transfer is enhanced with an increase in the nanoparticle volume fraction for all studied Rayleigh numbers.

Ammar I. Alsabery,Ammar I. Alsabery,Mohammad Ghalambaz,Taher Armaghani,Ali J. Chamkha,Ishak Hashim,Mohsen Saffari Pour,Mohsen Saffari Pour +7 more
TL;DR: The mixed convection two-phase flow and heat transfer of nanofluids were addressed within a wavy wall enclosure containing a solid rotating cylinder and Buongiorno’s model was applied to assess the local distribution of nanoparticles in the host fluid.
Journal ArticleDOI
Myth about nano-fluid heat transfer enhancement
TL;DR: In this article, the authors examined the effect of particle alignment with the direction of heat flow (temperature gradient) on the effective thermal conductivity, and demonstrated the reason of why the rate of heat transfer decreases by adding nano-particles for a fluid experiencing natural convection.

Melting dynamics of a phase change material (PCM) with dispersed metallic nanoparticles using transport coefficients from empirical and mean field models
TL;DR: In this article, the melting process of n-octadecane with dispersed Al2O3 nanoparticles in a semicircle is modeled with mean field models due to the conductivity and Brinkmann for viscosity, and an empirical model based on a least square fit to experimental data due to Corcione (2011).
