中文摘要:
      纳米流体作为一种新型高效的换热介质,其在螺旋通道中的应用被广泛研究。尤其是通过单相和两相模型对其流动及传热特性进行数值模拟,是近年来研究热点。介绍了单相模型中纳米流体物理参数的计算关联式,包括密度、比热、黏度及导热系数等,并分析了不同关联式对同一参数计算结果的影响;总结了单相模型下纳米流体在螺旋通道中的流动及传热特性,并与两相Lagrangian-Eulerian及Mixture模型下得到的结论进行对比分析;展望了未来研究的发展趋势。
英文摘要:
      As a new and high efficient heat transfer medium, nanofluid''s application in the helical channel is widely studied. Especially, the numerical simulation of flow and heat transfer characteristics of single phase and two-phase model has been focused recently. The caculation formula of physical parameters(density,specific heat, viscosity and thermal conductivity) of the nanofluid in single-phase model is introduced firstly. The influence of different correlations on the calculated results of witn the same parameter is analyzed. Then the flow and heat transfer characteristics of the nanofluid in single-phase model is summarized, which are compared with the results caculated from the Lagrangian-Eulerian and Mixture models.Finally, the development trend in the future is also prospected.
