High Pressure Release and Dispersion of Hydrogen in a Partially Enclosed Compartment

March 1, 2011
Author(s)
Kuldeep R. Prasad, Thomas G. Cleary, William M. Pitts, Jiann C. Yang
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 PRD

Fire Spread and Growth on Flexible Polyurethane Foam

October 18, 2009
Author(s)
William M. Pitts, Gregory Hasapis, Patrick Macatangga
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 spread

NUMERICAL SIMULATION OF FIRE SPREAD ON POLYURETHANE FOAM SLABS

March 17, 2009
Author(s)
Kuldeep R. Prasad, Roland Kramer, Nathan D. Marsh, Marc R. Nyden, Thomas J. Ohlemiller, William M. Pitts, Mauro Zammarano
The NIST Fire Dynamics Simulator (FDS) is used extensively by the fire protection engineer for performance based design and forensic analysis. The equations of motion describing the gas phase are relatively well known and the approximations in the various
