“…The corresponding critical temperature difference is also calculated from (Kalinin et al, 1976) DT cr ¼ 0:625½q cr sT The critical temperature is calculated to be 3 K. Above this point transition boiling occurs (Zuber, 1963). Nucleate boiling is less likely to occur in the water-LNG boiling system.…”

“…Standard film-boiling heat-transfer correlations, such as those by Berenson [41] and Kalinin et al [42], tend to underpredict the heat transfer between light hydrocarbons and metallic heaters. Furthermore, mixture effects on boiling are known to be significant, even for nearly pure fluids [43,44].…”

Globally, transport of liquefied natural gas (LNG) by ship occurs on a massive scale. The large temperature difference between LNG and water means that the LNG will boil violently if spilled onto water. This may cause a physical explosion known as a rapid phase transition (RPT). Since RPT results from a complex interplay between physical phenomena on several scales, the risk of its occurrence is difficult to estimate. There is need for a tool to quantify this risk in a straightforward manner, provided that the spill scenario and geometry are well known. In this work, we present a combined fluid-dynamic and thermodynamic model to predict the onset of delayed RPT. On the basis of the full coupled model, we derive analytical solutions for the location and time of delayed RPT in an axisymmetric steady-state spill of LNG onto water. These equations are shown to be accurate when compared to simulation results for a range of relevant parameters. The relative discrepancy between the analytic solutions and predictions from the full coupled model is within 2 % for the RPT position and within 8 % for the time of RPT. This provides a simple procedure to quantify the risk of occurrence for delayed RPT for LNG on water. Due to its modular formulation, the full coupled model can straightforwardly be extended to study RPT in other systems.

The use of natural gas has been on the increase for the past three decades and current consumption is expected to double by the year 2020. A rise in the number of transoceanic shipments will, logically, increase the risk of accidental spills, especially at terminal facilities. An LNG spill will generate a potentially dangerous cryogen vapour cloud. Consequently, the study of the rate of vapourization of this cryogen over water surfaces is of primary importance. Experimental measurements on confined LNG spills indicate the presence of high vapourization rates at early times after spillage. The present work introduces a vapourization model that has not been explored in previous studies. This model proposes the existence of a thin liquid layer at the cryogen-water interface that is not in thermodynamic equilibrium with the bulk of cryogen liquid. The implementation of the proposed model in a computer program allowed for the simulation of the boil-off process, and the estimation of the initial vapourization rates and heat transfer coefficients in confined and unconfined spills. The simulated cryogen spills offered a description of the vapourization rates that correlated well with experimental boil-off data. The simulations indicated the existence of early vapourization rates in the range of 0.03 to 0.06 gcm _2 s _1 , and an average initial heat transfer coefficient of 1576 Wm _2 K _1 for a typical LNG mixture.
