【摘要】：在氣液兩相流動(dòng)中,氣塞形成后可能會(huì)由于地形變化、輸送設(shè)備、或其他人為因素引發(fā)破裂,引發(fā)流體的流動(dòng)狀態(tài)變化及壓力波動(dòng)。為了深入了解段塞流流動(dòng)過(guò)程中氣塞破裂機(jī)理,建立了段塞流流動(dòng)過(guò)程中氣塞破裂的物理數(shù)學(xué)模型,以氣液兩相流流動(dòng)參數(shù)和管線幾何尺寸為研究對(duì)象,對(duì)氣液兩相流氣塞破裂所引發(fā)的壓力波動(dòng)進(jìn)行分析。結(jié)果表明:其他條件相同時(shí),相同長(zhǎng)度氣塞破裂引發(fā)的氣塞上游管線壓力降低的幅度隨上游管線持液率的增大而逐漸增大,隨管道直徑、液塞尺寸、混合物流速的增大而逐漸減小。
[Abstract]:In gas-liquid two-phase flow, the formation of gas plug may be caused by topographic changes, transportation equipment, or other human factors. In order to understand the fracture mechanism of gas slug during slug flow, a physical mathematical model of gas slug fracture during slug flow is established. The pressure fluctuation caused by gas slug rupture in gas-liquid two-phase flow is analyzed with the parameters of gas-liquid two-phase flow and the geometry of pipeline. The results show that the other conditions are the same. The decrease of the pressure of the upstream pipeline caused by the rupture of the same length gas plug increases gradually with the increase of the liquid holdup of the upstream pipeline, and decreases with the increase of the diameter of the pipeline, the size of the plug and the flow rate of the mixture.

【正文快照】： 氣液兩相和多相段塞流廣泛存在于石油、化工工業(yè)中,由于其流動(dòng)的間歇性和相分布的復(fù)雜性,目前對(duì)其研究仍處于探索階段[1-3]。在氣液兩相流動(dòng)中,氣塞形成后,可能會(huì)由于地形變化、輸送設(shè)備、或其他人為因素引發(fā)破裂。氣塞破裂后,由于作用在流體上力的變化,會(huì)導(dǎo)致流體的流動(dòng)狀態(tài)，
