Vacuum, gravity flow, and other solids discharge, according pipeline flow chart meters ( pid ) equipment layout of the elevation requirements
對真空、重力流、固體卸料等情況，一律按管道儀表流程圖（ pid ）的標高要求布置設備。 -
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
數學模型的建立過程中，對于液膜層流流動，直接對波形管內的降落液膜進行理論分析，得出液膜層流流動下數學模型的解析式；對于液膜湍流流動，由於湍流流動的復雜性，再加上所採用的波形管對湍流流動的影響，直接對降落液膜進行理論分析建立數學模型是極其復雜的，通過採用以前一些研究者得到的理論分析與實驗結果，並引入與波形管的形狀特徵參數有關的修正系數k ，建立液膜在湍流流動下的數學模型。
