Software User's Manual for the RAILCAR4.1 Toxic Industrial Chemical Source Characterization Program.

摘要

This document discusses the use of the RAILCAR4.1 Toxic Industrial Chemical Source Characterization Program to analyze a scenario in which there is a release of a toxic industrial chemical from a transport or storage tank, such as chlorine released from a rupture in a 90 ton railcar. The RAILCAR4.1 program addresses a knowledge gap associated with releases of pressurized liquid by providing an accurate characterization of the vapor source resulting from the liquid jet. The mist pool theory underlying the RAILCAR4.1 pressurized liquid source characterization was validated by the Jack Rabbit pilot tests and field trials, and the program was calibrated to match measured data. RAILCAR4.1 also predicts source terms for other chemicals that result in plumes or boiling or evaporating liquid pools. RAILCAR4.1 expands upon RAILCAR4 by adding a graphical user interface and providing output that can be entered into hazard assessment models used by emergency responders to better protect the public and warfighters from these types of incidents.
