CAVITATION OF LNG IN ULTRASONIC FLOWMETERS - CFD MODELLING |

- Abstract:
- In this paper a possible cavitation of LNG in ultrasonic flowmeters is investigated. The cavitation is an unwanted effect which can occur especially near the ultrasound transducer mountings where sharp edges at the wall can appear. By means of numerical modelling we predict pressure drops which can occur near the pockets in front of the ultrasound transducers. We then calculate a minimal sub-cooling of LNG below the bubble point temperature for which the cavitation can be avoided for various velocities and pressures in the fluid.
