11. Helium Dispersion in an Attached Single-Car Residential Garage with and Without Vehicle
Series: Technical Note (NIST TN)
Report Number: 1731
Published: 10/2/2012
Authors: William M Pitts, Jiann C Yang, Marco G Fernandez, Kuldeep R Prasad
Abstract: The dispersion and loss of helium inside a single-car residential garage attached to a single-family house was experimentally characterized by recording time-resolved helium concentrations at multiple locations in the garage and at a single locat ...

13. NATURAL AND FORCED VENTILATION OF BUOYANT GAS RELEASED IN A FULL-SCALE GARAGE: COMPARISON OF MODEL PREDICTIONS AND EXPERIMENTAL DATA
Published: 12/19/2011
Authors: Kuldeep R Prasad, William M Pitts, Marco G Fernandez, Jiann C Yang
Abstract: Increase in the number of hydrogen fueled applications in the marketplace will require a better understanding of the potential for fires and explosion associated with the unintended release of hydrogen within a structure. Predicting the temporally ev ...

14. Experimental Characterization of Helium Dispersion in a -Scale Two-Car Residential Garage (NIST TN 1694)
Series: Technical Note (NIST TN)
Report Number: 1694
Published: 3/29/2011
Authors: William M Pitts, Jiann C Yang, Marco G Fernandez
Abstract: A series of experiments are described in which helium was released at constant rates into a 1.5 m 1.5 m 0.75 m enclosure designed as a -scale model of a two car garage. The purpose was to provide reference data sets for testing and validating c ...

15. A NUMERICAL STUDY OF THE RELEASE AND DISPERSION OF A BUOYANT GAS IN PARTIALLY CONFINED SPACES
Published: 3/4/2011
Authors: Kuldeep R Prasad, William M Pitts, Jiann C Yang
Abstract: Development of the hydrogen economy will require a better understanding of the potential for fires and explosions associated with the unintended release of hydrogen within a structure. The ability to predict the mixing and dispersion behavior of hydr ...

16. High Pressure Release and Dispersion of Hydrogen in a Partially Enclosed Compartment
Published: 3/1/2011
Authors: Kuldeep R Prasad, Thomas George Cleary, William M Pitts, Jiann C Yang
Abstract: The study of compressed hydrogen release from high-pressure storage systems has practical application for hydrogen and fuel cell technologies. Such releases may occur either due to accidental damage to a storage tank or connecting piping, or direct ...

17. Vertical Release of Hydrogen in a Partially Enclosed Compartment : Role of Wind and Buoyancy
Published: 1/25/2011
Authors: Kuldeep R Prasad, William M Pitts, Jiann C Yang
Abstract: The natural and wind driven mixing and dispersion of hydrogen released in an accidental manner in a partially enclosed compartment with two vents is investigated using theoretical tools. A simple analytical model is constructed to predict the entra ...

18. Effect of wind and buoyancy on hydrogen release and dispersion in a compartment with vents at multiple levels
Published: 11/30/2010
Authors: Kuldeep R Prasad, William M Pitts, Jiann C Yang
Abstract: The natural and forced mixing and dispersion of hydrogen released in an accidental manner in a partially enclosed compartment with vents at multiple heights is investigated using theoretical tools. The key to the analysis is determination of the po ...

19. Fire Spread and Growth on Flexible Polyurethane Foam
Published: 10/18/2009
Authors: William M Pitts, Gregory Hasapis, Patrick Macatangga
Abstract: A series of experiments designed to characterize fire spread and growth on flat samples of commercial non-fire-retarded flexible polyurethane foam have been performed. 1.2 m × 1.2 m square sections of foam were ignited along one edge, and the fire s ...
