Natural convection heat transfer in concentric annuli with nanofluids

Wang Wenlong1,Xu Xu1,Wang Yufei1,Fan Liwu2,Yu Zitao2(1.College of Metrology and Measurement Engineering,China Jiliang University,Hangzhou 310018,China; 2.Institute of Thermal Science and Power Systems,Zhejiang University,Hangzhou 310027,China)  
Natural convection in horizontal annuli with Ag-water nanofluids was investigated by a numerical study.And particle volume fraction and the ratio of annuli were studied for the evaluation of heat transfer properties in the annulus.It was observed that heat transfer performance increased and heat transfer in natural convection changed from conduction to convection with an augmentation of Rayleigh number.The average Nusselt number was reduced with the increase of the nanoparcticles volume fraction.It became more significant at higher particle volume fraction.The average Nusselt number has decreased with the augmentation of the radius ratio,especially at low radius ratio.
