IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishAn accident involving a two-phase release can result in serious consequences for people as well as the environment. Consequently, tools are needed to give accurate predictions of the discharge rate, physical state, composition of released material, and chocked pressure in order to improve process safety efficiency. This paper discusses possible approaches to the examination of two-phase critical releases and presents a slip equilibrium model which provides critical flow rate, critical pressure, and phase fraction of the two phases emerging from an accidentally broken pipe containing a liquefied gas mixture under pressure. Comparisons between experimental critical flow rates and model predict ions are favorable in both monocomponent and multicomponent mixtures.

| Abstract: | An accident involving a two-phase release can result in serious consequences for people as well as the environment. Consequently, tools are needed to give accurate predictions of the discharge rate, physical state, composition of released material, and chocked pressure in order to improve process safety efficiency. This paper discusses possible approaches to the examination of two-phase critical releases and presents a slip equilibrium model which provides critical flow rate, critical pressure, and phase fraction of the two phases emerging from an accidentally broken pipe containing a liquefied gas mixture under pressure. Comparisons between experimental critical flow rates and model predict ions are favorable in both monocomponent and multicomponent mixtures. | |
