应用传热—传质类比原理于加罩转—静盘系统，通过盘缘轴向进气实验模型的研究，用萘升华法得到加罩转—静盘系旋转盘表面的局部和平均换质规律，从而类比出旋转盘的局部和平均的换热规律。文章分析了系统的几何尺寸（主要是间隙比Ｇｃ、间距比Ｇｓ）、旋转雷诺数Ｒｅθ和流量系数Ｃｗ对换质的影响。并用实验方法给出准则关系式，且对这种研究方法给出了误差分析结果。 Applying the theory of heat transfer and mass transfer to adding shroud-static disk system, the partial and average exchange of the surface of the rotating disk with the capstan-static disk system was obtained by the naphthalene sublimation method through the experimental study of the axial gas inlet of the disk rim Law, so as to analogy out of the rotating disk and the local average heat transfer law. In this paper, the influence of system geometry (mainly gap ratio Gc, pitch ratio Gs), rotational Reynolds number Reθ and flow coefficient Cw on the mass transfer was analyzed. The relational formula of the criterion is given by experimental method, and the error analysis result is given for this research method.
