關(guān)于VOF中的fluid volume 的概念(polyflow和fluent)
|
| 在polyflow中VOF設(shè)置inital material fraction 時,guide手冊上提到“ When tracking a single fluid, the fluid is determined to be present wherever the fluid fraction is between 0.5 and 1;。。。. Similarly, the fluid is determined to be absent wherever the fluid fraction is lower than 0.5, but it is recommended that the empty regions have a value of 0. By default, the initial fluid fraction is set to 0 throughout the domain.” 我的理解是計算域中體積百分比,為0的話是指計算域中初始無熔體,為1的話是指計算域中充滿熔體,不知道這樣理解是否正確? 我也做了為0,為1,為0.5的模擬。為0和為0.5差不多,但是為1的話計算就非?,只出了一個flur的圖(其他兩個都有200多個圖), 在fluent中VOF也有fluid volume fraction,各位大俠能好好解釋一下嗎? |
