    Abstract
  • To reduce the damage caused by particulate matter to equipment operation and to effectively control the particle concentration in oil, the pseudo-homogeneousz-flow mathematical model of suspended particles in oil was established using the continuum theory of liquid-solid two-phase flow. The dynamic characteristics of the oil containing particles were studied; the oil velocity and pressure and the distribution of particle velocity and concentration were analysed for varying particle concentration using the model. The results showed a good agreement between the experimental data and the results attained by the characteristic line method. The jump amplitude value of oil velocity and pressure decreases with increase in particle concentration; however, the jump amplitude value of particle velocity and concentration increases with increase in particle concentration. The distribution of particle concentration is substantially influenced by the oil pressure. The jump moments of the pseudo-homogeneous flow velocity and pressure take place are 1/4 pulsating period odd times, 1/8 pulsating period odd number and 1/4 pulsating period even times, respectively, at the beginning, middle, and end of the pipeline.
