Title: Burro-series gas-concentration contours

Abstract

Gas concentration contours generated from the data taken during the Burro series experiments 8 and 9 are presented. The contours are presented as a function of time in both a horizontal and a vertical format for several areas within the array.

    The Burro series of field experiments at China Lake, California, in 1980 was conducted to study the transport and dispersion of vapor from spills of LNG on water. The wind-velocity data were processed to define the turbulence in terms of the Reynolds stress tensor. Correlation coefficients for pairs of the six components of this tensor, were found to give statistical support for causal links between some of the Reynolds stresses. The LNG spill had significant effects on both the mean flow and turbulence only during the Burro 8 experiment (very low wind speed, stable atmosphere) and at only one ofmore » the turbulence stations. The mean-flow kinetic energy, U/sup 2//2, was dampened proportionately more than the turbulent kinetic energy, q/sup 2//2. The Burro gas-concentration data were processed to determine peak-to-mean concentration ratios for 10-s-average samples. Although many air-pollution data sets fit two-parameter lognormal distributions, four-parameter lognormal distributions are required to fit the Burro data. This is interpreted to mean that the data measures at a given sensor represent gas parcels with variable histories of mixing by the turbulent flow. 26 figures, 15 tables.« less

    During the summer of 1980, the Burro series of liquefied natural gas (LNG) spill experiments were performed at the Naval Weapons Center, China Lake, California. These experiments involved 8 spills of LNG and one of liquid nitrogen, each of approximately 40 m/sup 3/, onto water. A large array of instruments was used to make measurements of gas concentration, temperature humidity, heat flux from the ground, and turbulence within the dispersing gas cloud. A separate instrument array made measurements of the wind field both upwind of the spill and over the area in which the gas was dispersing. Volume II containsmore » appendices for: wind field data and flowlines; horizontal gas concentration contours; and vertical gas concentration contours.« less

    A series of LNG spill experiments (Burro series) were conducted at the Naval Weapons Center, China Lake, California. This report presents observations and analysis of data obtained from Burros 2 through 9. Topics discussed include the interaction of the wind field and gas cloud, LNG vapor dispersion, ground heat transfer, humidity enhancement, differential boiling of LNG, and rapid phase transitions (RPTs).

    During the summer of 1980, the Burro series of liquefied natural gas (LNG) spill experiments were performed at the Naval Weapons Center (NWC), China Lake, California. These experiments involved eight spills of LNG and one of liquid nitrogen, each of approximately 40 m/sup 3/, onto water. A large array of instruments was used to make measurements of gas concentration, temperature, humidity, heat flux from the ground, and turbulence within the dispersing gas cloud. A separate instrument array made measurements of the wind field both upwind of the spill and over the area in which the gas was dispersing. This reportmore » contains the data from these tests with an explanation of how and where the data were taken and the reliability of the instruments used to take it. It does not include analysis of the data, other than that which is necessary to understand the reliability of the data. Data analysis will be covered in a series of other reports.« less
