Réfrigération Résumé : Nucleate pool boiling heat transfer characteristics of refrigerant/oil mixture with diamond nanoparticles were investigated experimentally. The refrigerant is R113 and the oil is VG68. Experimental conditions include a saturation pressure of 101.3 kPa, heat fluxes from 10 to 80 kW m−2, nanoparticles concentrations in the nanoparticles/oil suspension from 0 to 15 wt%, and nanoparticles/oil suspension concentrations from 0 to 5 wt%. The experimental results indicate that the nucleate pool boiling heat transfer coefficient of R113/oil mixture with diamond nanoparticles is larger than that of R113/oil mixture by maximum of 63.4% under the present experimental conditions, and the enhancement increases with the increase of nanoparticles concentration in the nanoparticles/oil suspension and decreases with the increase of nanoparticles/oil suspension concentration. A correlation for predicting the nucleate pool boiling heat transfer coefficient of refrigerant/oil mixture with nanoparticles is proposed, and it agrees well with the experimental data of refrigerant/oil mixture with nanoparticles.
