Abstract
In support of the second phase of an integral computational fluid dynamics (CFD) simulation of a large scale chemical spill, this report presents the results from the CFD simulation of the building infiltration process of a heavy gas cloud. In the first phase of the present study, the growth and dispersion of a heavy gas cloud (LNG) from a liquid pool was successfully simulated. The second phase of the study attempts to capture the heavy gas infiltration process on a typical field observation building located approximately 200 meters downwind of the liquid pool. The primary motivation for the simulation was the prediction of heavy gas concentration inside the building as a function of space and time. The extreme usefulness of this investigation stems from the fact that the presence of a hazardous situation can be substantiated and analyzed without the need for an expensive experimental study or the endangerment of life. This report contains the prediction, in numerical and graphical form, of the development of LNG concentration, temperature distribution, and flow field, based on the CFD simulation.
