摘要
依据液体二维不均匀流动、二维涡流扩散模型,提出一个雾沫夹带及沟流对塔板上液体分布影响的数学模型,得到该条件下的塔板效率计算公式.讨论雾沫夹带及沟流对塔板效率的影响.结果表明雾沫夹带及沟流的存在使塔板效率降低.
A mathematical model for liquid concentration on tray and a formula on tray efficiency are proposed considering of entrainment and channeling, under the condition of the two dimension non-uniform flow and two dimension eddy diffusion .The effects on plate efficiency with entrainment and channeling are discussed. The results are presented in the form of tables and figures. It is found that the entrainment and channeling reduces the plate efficiency and the different coefficients have the different effects.
