The Behavior of LNG Vapor Clouds: Wind-Tunnel Simulation of 40 M3 LNG Spill Tests at China Lake Naval Weapons Center, California

摘要

Wind-tunnel transient concentration data were obtained from modeling tests which reproduced gaseous dispersion from five different forty cubic meter or less liquefied natural gas (LNG) spills performed at China Lake Naval Weapons Center during the spring and summer of 1980. Comparisons in the transient concentration data between these modeled tests and the field tests indicated which parameters are dominant in the modeling process. Model tests which reproduced the wind shear and turbulence structure of the approach wind reproduced the concentration patterns measured at the field site. This result reinforced the predictive reliability of wind tunnel modeling of larger volume spills.
