Abstract
[Hong et al. 2008] proposed a hybrid method of Eulerian grids and Lagrangian particles to represent small-scale bubbles in large-scale water. In the simulation, bubbles rise freely in the water; however, bubble seeds are set at random at the bottom and they disappear as soon as they arrive at the water surface. [Patkar et al. 2013] also proposed a hybrid Lagrangian-Eulerian framework to visualize both small and large scale bubbles. A bubble that exits the spout of a water dispenser flows up in the water with changing its shape; however, they did not simulate the rupture process of bubble. Then, [Mukai et al. 2012] tried a rupture simulation by using MPS method; however, it did not consider the high density ratio of the water to the air so that the bubble ruptured gradually. Therefore, this paper proposes a method of bubble rupture simulation, where a wave is generated after a bubble has ruptured rapidly, by considering the high density ratio of the water to the air.
[Hong et al. 2008]提出了一种欧拉网格和拉格朗日粒子的混合方法来表示大尺度水中的小尺度气泡。在模拟中,气泡在水中自由上升;然而,气泡种子是在底部随机设置的,它们一到达水面就消失了。[Patkar et al. 2013]还提出了一种混合拉格朗日-欧拉框架来可视化小尺度和大尺度气泡。饮水机壶口的气泡会随着形状的改变而向上流动;然而,他们没有模拟气泡的破裂过程。随后,[Mukai et . 2012]尝试使用MPS方法进行破裂模拟;然而,它没有考虑到水与空气的高密度比,使气泡逐渐破裂。因此,本文提出了一种气泡破裂模拟方法,即考虑到水与空气的高密度比,在气泡迅速破裂后产生波浪。
