Research on vortexes of cross flow past a horizontal circular cylinder by PIV system;
应用PIV系统研究横流中近壁水平圆柱绕流旋涡特性
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。
Main advances of research on vortices in pump sumps;
水泵进水池旋涡研究的主要进展
Based on flow field analysis,it shows that owing to the wakes behind the upstream suction pipe,the downstream flow becomes more turbulent and appears with obvious free-surface vortices and submerged vortices in complicated movement.
本文在玻璃水槽内对不同管间距条件下的吸水管周围进行了大量的PIV流场量测实验,通过流场分析显示,上游吸水管的尾流作用加剧了下游吸水口的水流紊动强度,流场多处出现表面旋涡和水内旋涡,其运动形态复杂多变。
The vortices flow in the blade passages and the influence of the eccentric inlet of the multi-blade centrifugal fan for air-conditioner have been analyzed numerically by using commercial CFD code.
在“前盘”附近,蜗舌下方的叶道中气流几乎停滞,蜗舌下游叶道为回流和尾缘旋涡所充满,至临近蜗壳出口侧,前缘旋涡逐步形成、发展并融合尾缘旋涡,最后衰减、消失。
Based on the previous studies of cold experiment and modeling, the numerical simulation of combustion characteristics of low NOx swirling coal-fired furnace was carried on using the CFD software, STAR-CD3.
在冷态实验和数值研究的基础上,采用STAR-CD软件对旋涡式低NOx煤粉燃烧器进行了热态模拟,分别得出了燃烧器内还原区和燃尽区的燃烧特性。
