DEGADIS:

DESCRIPTION

The DEGADIS model was originally developed for the U.S. Coast Guard and the Gas Research Institute primarily for simulation of the dispersion of cryogenic flammable gases. Subsequent work sponsored by the U.S. Environmental Protection Agency extended DEGADIS for simulation of the dispersion of vertical jets. Implementation of DEGADIS on a personal computer was sponsored by the Gas Research Institute and the American Petroleum Institute.

Basic information concerning the theoretical development of DEGADIS v2.1, its applicability, and its general implementation may be obtained from "User's Guide for the DEGADIS 2.1 Dense Gas Dispersion Model," Tom Spicer and Jerry Havens, EPA-450/4-89-019, November 1989. This document is available through the National Technical Information Service, 5285 Port Royal Rd, Springfield, VA 22161, Order no. PB90-213893. Documentation pertaining to the use of DEGADIS on a PC is available from the Gas Research Institute or the American Petroleum Institute. The Gas Research Institute report provides specific guidance on liquefied natural gas (LNG) vapor dispersion.
