为了建立膜生物反应器污水处理装置中气泡流动的数值预测方法,提出了一种预测污染体系中单个气泡流动的界面跟踪方法,并对液体中的气泡进行了实验研究。通过考虑表面活性剂对气泡运动的影响,建立了阻力和升力模型。开发了实现这些模型的多流体模型。
英文摘要
An interface tracking method for predicting single bubbles in contaminated systems was developed and experiments on bubbles in liquids were carried out to develop a numerical method for predicting bubbly flows in wastewater treatment devices based on membrane bioreactor method. A drag and lift forces were modeled by accounting for the effects of surfactant on bubble motion. A multi-fluid model implementing these models was developed.
