This paper reviews the methods developed to calculate the critical flow during the emergency pressure relief of a chemical reactor or a storage tank. The fundamentals of the single-phase and two-phase critical flows are discussed but the emphasis is mainly on the simplified formulations recently developed (DIERS) in order to provide quick and simple-to-use vent sizing methods appropriate for safety requirements.
