Abstract
The evolution of stratified liquid natural gas (LNG), from its formati on to its breakdown, is considered. Experimental observations have sho wn this evolution to consist of two principle phases: a quiescent, sta ble phase 1 where the interface between the two layers is stationary; and an unstable phase 2 characterised by a migrating interface and cul minating in a rollover. Mathematical models of the two phases are prop osed and considered separately. For phase 1 a parametric solution is d erived; the corresponding numerical solution of phase 2 equations is g iven and shown to compare well with experimental data. (C) 1997 Elsevi er Science Ltd.
