| Abstract: |
| Running oil inevitably produces particulate matters, and the particulate matters will affect the normal use of the oil,even cause equipment failure.Thus it is of great significance to analyze the dynamic characteristics of oil containing suspended particles,and to understand how oil and particles change their properties under different pressures.A dynamic model of suspension flow containing suspended particles is established by means of the theory of two-phase fluid mechanics,and numerical solutions are obtained by characteristic line method.The numerical results are compared with the experimental data and show good consistency; pulsation trend of each phase of suspension flow was analyzed under different system pressures.The result shows that the pulsation amplitude of each phase of the flow field increases with the system pressure increase.The pulse moments of the parameters of each phase at the pipeline head and the pipeline terminal respectively occur at the odd and even multiples of a quarter of the pulsation period (T/4),while the pulse moments of the parameters of each phase inside the pipeline occur at the odd multiples of T/8.The velocity of suspended particles will be affected by the oil drag force,and its tendency is consistent with the oil velocity.The trend of particle concentration distribution is opposite to that of the oil pressure. |
