5) rollover
[英]['rəʊləʊvə(r)] [美]['rol'ovɚ]

涡旋
1.
Heat convection characteristic in LNG storage tank when LNG stratification and rollover

LNG储罐分层涡旋事故的热对流特性
2.
Liquefied Natural Gas(LNG) is a kind of high quality and clean energy,but many accidents have taken places since it was widely used,and stratification is the necessary condition for rollover.
液化天然气(LNG)作为一种优质洁净的能源兴起以来,发生过多起储运失稳事故,其中分层是导致涡旋的必要条件。
3.
As the model takes no account of the consequences of boil off rate on density difference and can not interpret the acceleration of the interface's descending before rollover, the paper developed an advanced model which has 4 phases instead of 3 of the old one, and this phase dividing is more reasonable.
介绍了液化天然气涡旋问题和Bates-Morison模型,并针对Bates-Morison模型没有考虑蒸发率对密度差的影响、不能解释涡旋发生前分界面加速下降这一事实等缺陷,提出了改进四阶段涡旋模型。

[英]['vɔ:teks] [美]['vɔrtɛks]

When the gas enters the stack by tangent and forms vortex,the negative pressure is formed in center of the flow field.
对新型烟囱技术特征和流场结构的分析认为:由于切向进气,烟气形成旋涡,流动阻力低于普通烟囱,压力损失减少,所以更节能;流场中心形成负压,水、雾等比尘粒小,但比空气大(重)的轻质组分集中在中轴地带随烟气排出,不会腐蚀内壁;因为旋涡流动的存在,提升了烟气排放高度,有更好的环保效果。
补充资料:半自由旋涡
分子式:
CAS号:
性质:当流体作回转运动时,自由旋涡的一部分能量即行损失掉,于是自由旋涡即变成半自由旋涡,又称为准自由旋涡(quasi-free vortex)。一般,回转圆周速度u0与回转曲率半径r的若干分之一次方成反比的旋涡即为半自由旋涡。例如,在旋风分离器筒壁附近所产生的流体回转运动即属于半自由旋涡流动,此时,
