摘要
针对竖直管内液泛形成时管子入口截面含液率与液膜厚度增加的特点 ,本文建立了分析管内液泛问题的数学模型 ,并对数学模型进行数值计算 ,计算结果与管内液泛的实验值能较好的吻合 ,为研究管内液泛的问题提供了一种较好的分析计算方法 .
Based on the characteristic to form flooding that the liquid fraction is increased and the liquid film is thick in tube bottom, the model of gas and liquid two phase counter-current flow is set up to do a numerical analysis for flooding problem. And numerical calculation has been made to solve the mathematics-model. Comparing results calculated under normal temperature conditions with experimental results, they coincide well. It indicates that the model can be used to analyze the problem of gas and liquid two-phase counter-current flow and flooding.
