【摘要】：油液中含有颗粒物会影响设备的正常运行,考察不同初始速度条件下含颗粒油液的悬浮流中各相的动态特征,利用连续介质模型建立含悬浮颗粒油液的动力学模型,并通过特征线法进行数值求解,得到在不同初始速度条件下各相参数的变化趋势。结果表明:不同初始速度条件下管路始端、中段和终端油液的压力、流速都分别在T/4的奇数倍、整数倍、偶数倍时刻产生跃变,且它们的周期(T)都随着初始速度的增加而减小;悬浮颗粒的浓度分布与油液压力的变化趋势相反。
[Abstract]:The presence of particles in the oil will affect the normal operation of the equipment. The dynamic characteristics of each phase in the suspension flow with different initial velocity are investigated, and the kinetic model of the oil containing suspended particles is established by using the continuum model. The change trend of phase parameters under different initial velocities is obtained by means of the characteristic line method. The results show that under different initial velocities, the pressure and velocity of the oil at the beginning, middle and end of the pipeline are at the odd times of T / 4, integer times and even times, respectively, and their periodic (T) decreases with the increase of initial velocity. The concentration distribution of suspended particles is opposite to that of oil pressure.
