Distribution of flow vector, fluctuating velocity, turbulent kinetic energy, turbulent intensity and particle concentration were discussed. 本文对流场、脉动速度、颗粒浓度、湍动能、湍流强度等的分布做了讨论。
Horizontal swirl, axial tumble and the distribution of turbulent kinetic energy are very important for fuel atomization and mixture formation. 水平方向的涡流、轴线方向的滚流以及湍动能的这种分布特性都有利于燃油的雾化以及与空气的混合。
Circumfluence area and a maximum turbulent kinetic energy area are located in the vicinity of meniscus. 在弯月面附近出现明显的钢液回流区;
The standard deviation of static pressure, turbulent kinetic energy, velocity of range nozzle and static pressure of spreader nozzle were almost in direct proportion to inlet pressure. 而副喷嘴出口湍动能和速度的标准差随主喷嘴直径或入口压力增大产生较大的无规律变化。
It is found that the turbulent kinetic energy and the turbulence intensity in a static mixer both increase as a function of the number of twist elements per section. 按单叶片、双叶片组合、三叶片组合、四叶片组合顺序静态混合器内湍动能与湍流强度呈递增趋势;
