On the selection of gas-liquid two-phase flow patterns
Thread Content
In the low-temperature methanol washing unit, there are many gas-liquid pipelines that narrow in their vertical sections; this is done to facilitate the better transport of gas-liquid two-phase flow. I have a question for everyone: which fluid pattern is more suitable for gas-liquid two-phase flow in vertical pipes – bubble flow, annular mist flow, or slug flow and foam flow? Thank you
How are bubble flow, annular mist flow, slug flow, and foam flow classified? Is it related to flow velocity? Is it still related to the material being conveyed?
The gas-liquid two-phase flow is generally a bubbling flow, which is a form of gas entrainment in the liquid~! If it is annular mist, the heat exchange efficiency of the heat exchanger will decrease or gas blockage may occur
Flow pattern classification is related to various factors such as volume gas content, fluid velocity, and the properties of the material. For determining flow patterns, reference can be made to the \"Guidelines for Selecting Pipe Sizes in Process Units of Petrochemical Enterprises\" SH 3035-1991
