压力对消泡器消泡能力的影响实验研究与数值模拟

Experimental Study and Numerical Simulation of Pressure Effect on Anti-foaming Ability of Foam Breaking Device

摘要:

泡沫钻进中，消泡有十分重要的环保和经济意义。但在实际生产中，现有的消泡器不能很好地达到消泡的要求,这就需要对消泡器做更进一步的深入研究。通过建立消泡器室内试验台,进行压力对消泡能力影响的试验,确定了压力与消泡率的关系，同时利用FLUENT 软件中的VOF模型对泡沫在消泡器中流动时压力变化进行了数值模拟,模拟结果与实验结果是相符的。

Abstract:

Foaming breaking is very important for environmental protection and economic development in foam drilling, but current foam breaking device cannot meet the requirements. Further study was made by establish the indoor test platform for foam breaking device, the relation between pressure and foam breaking rate was determined; numerical simulation was made on floating pressure change in foam breaking device by VOF model of FLUENT software, and the result was the same to the experiment.
