Recent publications

Researchers at GexCon has been actively involved in process safety technology since the early 1970s. Our research activities cover state-of-the-art software development, extensive validation of implemented models in the CFD codes FLACS and DESC, laboratory to large-scale dispersion and explosion experiments, accident investigations, hydrogen safety and wind energy.

The activities related to process safety started at Chr. Michelsen Institute (CMI) in 1970, continued at  Christian Michelsen Research (CMR) from 1992, and has since 2001 been organized under GexCon, a wholly owned subsidiary to CMR.

Whenever possible, GexCon seeks to share results from our research activities with the global community through presentations at international conferences and publications in scientific journals. Some recent publications are listed below, and selected publications from our work over the last 40 years are listed in the ARCHIVE.
