To simulate the diffusion of the vortex sheet into the flow field as time goes on, Koumoutsakos' analytical solution is employed, in which an effective vorticity flux is derived and used for solving the vorticity diffusion equation. The solution is then discretized into blobs (called "-blobs") in the vicinity of the boundary.

而涡片之环量随时间扩散进流场之现象则藉由Koumoutsakos之理论，以边界上之等效涡度通量求解扩散方程式，得解析解后，再将之离散为边界附近之新涡泡。

Only the fragrance of drink residues, in the glass of the dark speaking out flirting words as soft as cheese In her mouth, a crow holds a slice of cheese, on a tree A fox is flattering, below the tree The crow smiles happily, the cheese falls into fox's mouth The story spreads out and come down to us It is the story about you and me For a beautiful word we walk up to cliff, and dash ahead regardless of our life until our black hair is burned up by the fire of time we turn around and look at the fox and the crow the man and the woman those similar loving words and eye's expression La Fontaine we are here listening to ancient chime in the dark to whispering sound of guitar to flicker of well water in moonlight to flower boldly blooming arms to moist footstep of night traveler Perhaps the sunshine is burning far But we are growing up in the dark We grown up in Plato's allegory of the cave

只有酒香沉淀下来，在黑暗的杯底说出奶酪一样柔软的情话乌鸦在树上衔一片奶酪狐狸在树下谄媚乌鸦嘻笑，奶酪落进狐狸嘴里故事无翼而飞，就这样流传下来这是关于你和我的故事为了一句美丽的言辞我们走向悬崖奋不顾身直到青丝被岁月的流火燃尽才顾得上分辨狐狸和乌鸦男人和女人，那些相仿的情话，貌似的眼神拉封丹我们在这里在黑暗中听古老的的钟声听若有若无的吉它声听井水在月光下颤动听花朵大胆地张开臂膀听夜行者潮湿的脚步也许阳光在远方燃烧但我们是在黑暗中长大我们成长于柏拉图的洞穴比喻
