Despite many applications, the three phase foam is so complicated and far from being fully understood. Drainage is critical to foam decay, so the effect of particles on foam drainage has been investigated in this research to better understand the complex three phase foam. The power law relationship, drainage regime, foam permeability and the residual solid particles were investigated with different particle concentration, particle hydrophobicity and particle size. It was found that the power law index increased with the increasing of particle concentration and particle hydrophobicity, which indicates the transition of drainage regime from node dominated to Plateau border dominated. It was also found that the medium size particles could increase the Plateau border viscous loss more obviously. Foam permeability with different particles was also discussed via fitting the viscous loss of both Plateau border and nodes. Finally, residual solid particle was used to study the particle behaviour during the free drainage after forced drainage. This research could help us better understand the drainage of three phase foam.

颗粒对泡沫排水的影响

尽管有许多应用，但三相泡沫非常复杂，而且远未被完全理解。排水对于泡沫衰减至关重要，因此本研究研究了颗粒对泡沫排水的影响，以更好地了解复杂的三相泡沫。研究了不同颗粒浓度、颗粒疏水性和颗粒尺寸下的幂律关系、排水状况、泡沫渗透性和残留固体颗粒。研究发现，幂律指数随着颗粒浓度和颗粒疏水性的增加而增加，这表明排水状况从节点主导向高原边界主导的转变。研究还发现，中等尺寸的颗粒可以更明显地增加Plateau边界粘性损失。通过拟合Plateau边界和节点的粘性损失，还讨论了不同颗粒的泡沫渗透性。最后，利用残余固体颗粒研究强制排水后自由排水过程中的颗粒行为。这项研究可以帮助我们更好地了解三相泡沫的排水。
