Railcar Sensitivity Analysis

Abstract

This sensitivity analysis was designed to determine how certain input parameters would affect the output parameters of the RAILCAR computer program, a tool used to predict the physical characteristics of a toxic industrial chemical (TIC) release from a transport container. Three vignettes (evaporating liquid pool, boiling liquid pool, stationary vapor cloud) were studied; parameters were identified for each that significantly affected the output source characterizations. While some input parameters only had an influence on one vignette, others affected all three. Hole diameter and boiling temperature had significant effects on all three vignettes, but tank pressure, critical temperature, and vapor density did not affect any of the output parameters (within the scope of this analysis).
