INVESTIGATION OF FLUID TRANSIENTS IN PIPELINES WITH AIR ENTRAINMENT
T. S. Lee (Singapore), D. T. Nguyen (Singapore), H. T. Low (Singapore) and J. Y. Koh (Singapore)
Abstract:
This paper introduces a variable wave speed model for the calculation of fluid transients in pipelines with air entrainment in which wave speed at every point along the pipeline depends on the local pressure and local air void fraction at that point. A set of experiments was carried out in a single pump pipeline system to test the fluid transient behaviour for the case of pump trip due to power failure and to validate the numerical model. In comparison with experimental results, numerical results show that the variable wave speed model can provide a closely transient pressure prediction for the first pressure peak. However, there are the discrepancies between the computational predicted results and the experimental results for the next pressure surges especially in the rate of pressure damping. This limitation points to the need for further refinements of the variable wave speed model to improve the accurate of the pressure transient prediction.
Keywords and phrases:
liquid-gas two-phase flows, bubbly flows, pressure transient, air entrainment, variable wave speed.
