Modeling Aerosol Rainout
MetadataShow full item record
The AIChE Center for Chemical Process Safety has coordinated research efforts aimed at characterizing and predicting the behavior of aerosols during accidental releases. Field tests designed to be used for validation of a predictive model (RELEASE) showed that aerosol rainout was a significant factor under the test conditions. In addition to summarizing the RELEASE model and the data from the field test, Woodward and Johnson (1999) corrected the measured aerosol rainout to account for the experimental conditions; their corrections rely on an initial estimate of the jet velocity that is not limited by choked flow conditions (sonic velocity). This paper discusses the jet expansion zone and considers how other models of the jet expansion zone influence the predicted aerosol rainout of the RELEASE model.
