The paper first report the status of gas flow in the chamber channels during the sublimation which was discriminated as viscus flow. The digital solution of the gas flow and heat transfer in the chamber channel was gotten by using CFX4. 0 software.

本文首次对冻干升华过程中冻干箱内通道里的气体流动状态判定为粘滞流，并用流体力学计算软件CFX4.0对冻干箱通道内的流动和传热进行了数值求解，给出了通道内气体流动的流线图和温度场图。

Flow disciplinarian of different PH indicator polymer solution and newtonianliquid in annulus line had been studied, and found speed distributing, vortex,streamline of annulus line, analytic flow field distributing in annulus and eccentricsituation and compared the results with prevenient schloar, some results different fromprevenient results are get, shch as the relation of average velocity and maxiumvelocity is not less with the viscosity exponent under the annular line, the fluid speedaffect the relation.

应用 PIV 分别研究了不同浓度的聚合物溶液以及牛顿流体在垂直环空管道中的流动规律，得到了环空管道中流体的速度分布情况、涡量情况、流线情况，分析了同心和偏心情况下环空管道内的流场分布规律，并与前人的计算结果进行了比较，得出了一些与以前不同的结论：同心情况下平均流速与最大流速的关系，并不是完全与粘性指数 n 值有关系，还与管道内流动的流动速度有关系，当速度较小时，两者的差别就小，速度大时，不符合这种规律。
