Wind tunnel site analysis of Dow Chemical Facility at Rocky Flats, Colorado

CER71-72RNM-FC-451.May 1972.Prepared for Research and Ecology, Rocky Flats Division, Dow Chemical Company.Includes bibliographical references.Tests were conducted on a model of the Dow Chemical Company plutonium recovery facility, Rocky Flats Division, and the surrounding topography to determine the dispersal and trajectories of potential effluents. Profiles of wind and turbulence over the facility were adjusted to forms expected for the given terrain. Dispersion and trajectory characteristics were determined by releasing a krypton-85 tracer gas from specific sources and sampling the plume downwind. Results suggest that the plumes depart only modestly from behavior suggested by the Pasquill-Gifford prediction methods. All results are tabulated and/or presented in a dimensionless manner suitable for prototype site evaluation

Data appendix to the behavior of LNG vapor clouds: wind-tunnel tests on the modeling of heavy plume dispersion: final report (July 1979-September 1981)

CER81-82DEN-RNM25.March 1982.Accompanying final report has title: The behavior of LNG vapor clouds: wind-tunnel tests on the modeling of heavy plume dispersion: final report, July 1979-September 1981.Visual and concentration measurements were made for a large number of continuous ground-level releases of heavy gases into a wind-tunnel boundary layer. These different plumes were not affected by any topographic or building wake influences. The experiments provided a broad coverage of the variable range of source gas specific gravity, source gas flow rate, and approach flow wind speed. From an investigation of the physical similarity between plumes, the permissible modeling distortion in source density, volume flux ratio, and length scale ratio was quantified. The concentration scaling theory which was previously limited to far-field behavior was extended to cover the entire range of plume concentrations. Generalized behavior models were constructed from the laboratory tests. These models were scaled up to atmospheric conditions. The range of atmospheric scenarios to which these laboratory data are applicable is summarized. Measurements on the behavior of transient dense plumes were also obtained.For Gas Research Institute contract no. 5014-352-0203

Wind tunnel site analysis of Dow Chemical Facility at Rocky Flats, Colorado, part II

Prepared for Research and Ecology, Rocky Flats Division, Dow Chemical Company.CER72-73RNM-JAP-TGH-16.March 1973.Includes bibliographical references.This report deals with two separate problems occurring at the Dow Chemical Company Plutonium Recovery Facility, Rocky Flats Division, namely the dispersion of potential effluents and the protection of parking areas from the destructive action of high velocity west winds by the use of shelterbelts. The dispersion study is a continuation of a previous study and consisted of modeling the geography, wind and turbulence profiles and effluent releases in a wind tunnel study. Dispersion and trajectory behavior was determined by the use of Krypton-85 as a tracer gas. The results reinforce the conclusion advanced in the previous study that Pasquill-Gifford prediction methods apply well to the site. The shelterbelt study consisted of evaluating the effects of porosity, barrier height and length, geometric configuration of barriers, parking lot orientation and wind approach angle upon the protection of parking areas from high velocity wind action in assaulting vehicles with abrasive particles. Tests were accomplished by observing the effectiveness of the wind in transporting a zinc oxide-mineral oil suspension. This effectiveness was correlated to velocity reduction and wind profile modification effectiveness of shelterbelts. It was found that the most effective use of shelterbelts could be accomplished if the parking lot were reoriented with the long side running in a north-south direction

Review of CFD Guidelines for Dispersion Modeling

This is the review of CFD (Computational Fluid Dynamics) guidelines for dispersion modeling in the USA, Japan and Germany. Most parts of this review are based on the short report of the special meeting on CFD Guidelines held at the International Symposium on Computational Wind Engineering (CWE2014), University of Hamburg, June 2014. The objective of this meeting was to introduce and discuss the action program to make worldwide guidelines of CFD gas-dispersion modeling. The following six gas-dispersion guidelines including Verification and Validation (V&V) schemes are introduced by each author; (1) US CFD guidelines; (2) COST/ES1006; (3) German VDI (Verein Deutscher Ingenieure) guidelines; (4) Atomic Energy Society of Japan; (5) Japan Society of Atmospheric Environment; (6) Architectural Institute of Japan. All guidelines were summarized in the same format table shown in the main chapters in order to compare them with each other. In addition to the summary of guidelines, the overview of V&V schemes and many guidelines of CFD modeling in the USA are explained
