Modelling boiling delay and transient level swell during emergency pressure relief of liquefied gases

摘要

A one-dimensional non-equilibrium model is presented for transient level swell during emergency pressure relief of liquefied gases. The model results are compared to small-scale pressure relief experiments. The effects of thermal non-equilibrium on level swell are summarized and it is shown that non-equilibrium effects are particularly important in small-scale vessels.
