- 摘要:
- 用颗粒轨道模型对基于激波控制的二维收缩-扩张(2-DCD)喷管中的气固两相流动进行了数值模拟，研究了1~60 μm不同直径颗粒的运动轨迹。研究表明，颗粒尺寸越小，粒子的随流性越好；颗粒尺寸越大，主流中的粒子与收缩段壁面碰撞越剧烈，无粒子区越大，二次流中的粒子对下壁面的碰撞越剧烈。
- Abstract:
- The numerical simulation of gas-solid two-phase flow in fluidic thrust vector nozzle based on shock wave control was carried out with a particle trajectory model. The moving trajectory of particles whose diameters are from 1μm to 60 μm was studied. The research result shows that the smaller the particle is, the better the flowing property becomes; the bigger the particle size is, the more violent the collision between the particles in the main flow and the wall in convergent region occurs; and the larger the region without any particle is, the more serious the collision between the particles in the second flow and lower wall in the nozzle becomes.
