Examples
- For newtonian fluid , the influence of the plate undulations , the reynolds number and the thickness of the film are shown by parameter studies ; for non - newtonian fluid , the shear - thinning coefficient on the film flow is shown by parameter studies
在薄膜流动过程中,考虑波形板的轮廓形状参数变化、流动中雷诺数的大小、薄膜厚度的变化以及非牛顿流体的剪切变稀系数对薄膜流动的流变特性影响。 - In the laminar flow regime , a analytical mathematical model is obtained by analyzing the film flowing in the wavy wall tube . in the turbulent flow regime , mathematical model almost ca n ' t be obtained directly because the turbulent flow in wavy wall tube is very complex , the model is obtained by quoting some results which are theorized by other studiers . in the part of experimental study , the flow form in the wavy wall tube is observed by transparent quartz glass wavy wall tube apparatus , the evaporation experiments are carried out in a 3 meters steel wavy wall tube , using glucose as the medium , heat transfer is invested , the heat transfer correlations of wavy wall tube evaporator are obtained
数学模型的建立过程中，对于液膜层流流动，直接对波形管内的降落液膜进行理论分析，得出液膜层流流动下数学模型的解析式；对于液膜湍流流动，由于湍流流动的复杂性，再加上所采用的波形管对湍流流动的影响，直接对降落液膜进行理论分析建立数学模型是极其复杂的，通过采用以前一些研究者得到的理论分析与实验结果，并引入与波形管的形状特征参数有关的修正系数k ，建立液膜在湍流流动下的数学模型。
