Spreading and Differential Boil-off for a Spill of Liquid Natural Gas on a Water Surface

摘要

A model for the unconfined spreading and evaporation of liquid natural gas (LNG) when spilled on a water surface has been developed. The model includes a model for differential boil-off of the LNG constituents. A listing of the computer code, LNGVG, developed for making these calculations is included. This code can be used to calculate effects for instantaneous, continuous or finite duration continuous spills. Calculations for two spill experiments conducted at China Lake have been made and are compared to the experimental data. (ERA citation 04:012449)
