Numerical Simulations of Atmospheric Releases of Heavy Gases Over Variable Terrain

The Lawrence Livermore National Laboratory (LLNL), under the sponsorship of the U.S. Department of Energy, is conducting safety research related to the possible consequences of liquefied natural gas (LNG) spills. Under this program, LLNL and the Naval Weapons Center (NWC) jointly conducted the Burro and Coyote series of LNG spill experiments at China Lake, California during 1980 and 1981 respectively (Koopman et al., 1982; Koopman, 1982). LLNL is concurrently developing models for use in predicting the vapor dispersion from LNG spills (Ermak et al., 1982).
