长尾喷管中粒子运动轨迹的数值模拟

Numerical Study of Particle Trajectories in a Nozzle with a Tail Pipe

利用颗粒轨道模型计算了长尾喷管两相流流场,确定了在与壁面发生完全弹性和完全非弹性碰撞情况下不同尺寸粒子的运动轨迹,比较了不同尺寸粒子之间以及完全弹性碰撞和非弹性碰撞之间长尾喷管中粒子运动的差异,得出了长尾喷管中粒子运动的某些规律。

Twophase flow field in a nozzle with a tail pipe is studied by using the trajectory model to define particle trajectories of different sizes under both fully elastic bounce and fully nonelastic bounce.Both particles of different sizes and particles under fully elastic bounce or fully nonelastic bounce are traced to find out the properties of particles flowing.Some of rules of particles flowing in a nozzle with a tail pipe have been obtained.
