输流管道压力脉动计算分析
Calculation Analyze of Pressure Pulsation in Fluid Flowing Pipeline
摘要
Abstract
Considering the influence of damp and pressure pulsation,the wave equation of fluid in the pipeline is established.The equation is solved with standing wave method and the expression of pressure pulsation and natural frequency of the fluid in three different boundary conditions are obtained.The exciting force produced by pressure pulsation inside an elbow pipe is analyzed and the curve diagram is given with the help of Matlab,which proved that the pressure pulsation is the main reason for pipe vibration.关键词
