Maplin Sands Experiments 1980: Dispersion Results from Continuous Releases of Refrigerated Liquid Propane

Trials on dispersion of heavy gas clouds

“…These experiments led to further experiments of similar desi n in which the scale of the ex eriments was inexperiments, organized bv HSE, were carried out during 1982-84 at Thorne Island by the National Maritime Institute (now NMI Ltd. and form the subject of this paper. The Thorney Island experiments are complementary to those carried out in the early 1980's at China Lake USA (Koopman et al [9]) and at Maplin Sands UK (Puttock et a2 [15]). Reviews of field experiments have been given by Puttock et al [16] and McQuaid [ I l l .…”

Investigation of entrainment and thermal properties of a cryogenic dense-gas cloud using optical measurement techniques

“…1 The properties of nitrogen and air are similar and the moisture content of the cloud is negligible for continuity considerations. In this case, we obtain d dx…”

“…Several experiments were motivated by the early interest in the related hazards. The Maplin Sands trials with LNG and refrigerated liquefied propane (Puttock et al [1]) or the Burro Series LNG experiments (Ermak et al [2]) should be mentioned in the context of large-scale field trials. Only the first experiment of the Burro trials was performed with LN 2 , which evaporated on a water surface, the other eight trials were performed with LNG.…”

Characterization of Medium-Scale Accidental Releases of LNG

“…Moreover, comparable values for m and m ev are reported, despite the differences in the boundary conditions characterizing the system from a thermal point of view. As it is possible to note, the majority of data have been collected for D p > 5 m (i.e., larger than D ∞ ), whereas a dearth of studies can be observed for D p < 1 m. Generally speaking, even if large-scale experimental scenarios have already been tested [26] and modelled [27], quite unexpectedly, small-and medium-scale experiments are rare, as recently observed also by Zhang et al (2018) [28]. To this aim, data on the mass evolution over time can be conveniently integrated by qualitative (e.g., images) and quantitative (e.g., thermocouples and pyrometers) analyses on the thermal aspects in the proximity of a pool fire [29].…”
