The liquid plug of length-specific and speed, and Research on hydrodynamic applied to liquid plug and liquid plug are to the shadow of separator separating property
Research is rung, belongs to oil-gas gathering and transportation system multi-phase separation technical field.
Background technology
In biphase gas and liquid flow multiphase pipeline, slug flow is a kind of most common flow pattern, and it is (normal in many operating conditions
Operation, pigging, throughput rate change etc.) under can all occur.Slug flow can be described as liquid plug and air full of whole cross-section of pipeline
The alternating flowing of (having liquid film below) is steeped, there is the characteristics of intermittent strong, pressure drop is high.Slug flow can be to conveyance conduit and downstream
Separation equipment brings totally unfavorable influence.Therefore, it is necessary to study slug flow hydrodynamic characterisitic and liquid plug to downstream separation
The influence of equipment, this is significant to ensureing gathering system safe and stable operation.
Slug flow can be generally divided into two major classes：The first kind is hydrodynamic force slug flow, is now blown afloat in pipeline by air-flow
Liquid phase bridges to tube top obstruction pipeline flow area and forms liquid plug, and it can be subdivided into common waterpower slug flow and by gas-liquid flow again
The slug flow that amount change induces, it is larger to there is general gas-liquid flow during this slug flow.Second class is the section that hypsography induces
Plug flow, life often is issued in low gas-liquid flow, now pipeline has descending connection upward slope structure, and liquid phase is stifled in the low-lying place's accumulation of pipeline
Gas passage is filled in, so as to form slug flow in upward slope section, the speed and length of this slug flow can reach very big (such as：Strongly
Slug flow), and with obvious periodicity.
Although this two classes slug flow formation mechenism is different, there is a common feature, that is, slug length and liquid plug speed
Degree has randomness；This randomness causes the research currently for slug properties of flow to be based on liquid C1-esteraseremmer-N sign in a period of time
The average value or statistical value of Parameters variation.In addition, for downstream separation equipment, it is especially poor to gas-liquid flowed fluctuation adaptability
Compact separation equipment, can not keep efficiently separating performance under all two phase flow operating modes.Therefore, slug flow is studied especially
