On the Ignition of Fuel Beds by Firebrands.

May 11, 2005
Author(s)
Samuel L. Manzello, Thomas G. Cleary, John R. Shields, Jiann C. Yang
An experimental apparatus has been built to investigate the ignition of fuel beds as a result of impact with burning firebrands. The apparatus allowed for the ignition and deposition of both single and multiple firebrands onto the target fuel bed. The

CF3I Stability Under Storage.

December 1, 2004
Author(s)
Michelle K. Donnelly, Richard H. Harris Jr., Jiann C. Yang
This research investigates the stability of iodotrifluoromethane (CF3I) during storage. For CF3I to be used as a fire extinguishing agent, it must be able to be stored for long periods of time at high pressure in metal containers without degrading and

Urban/Widlland Fires: Ignition by Embers

July 7, 2004
Author(s)
Samuel L. Manzello, Thomas G. Cleary, Jiann C. Yang
Urban-wildland fires have plagued the United States for centuries. Embers are produced as trees and other objects burn in urban-wildland fires. These embers are entrained in the atmosphere and may be carried by winds over long distances. Hot embers

On the Interaction of a Liquid Droplet with a Pool of Hot Cooking Oil

November 1, 2003
Author(s)
Samuel L. Manzello, Jiann C. Yang, Thomas G. Cleary
An experimental study is presented for distilled water droplets impacting on a heated pool of cooking oil. The impaction process was recorded using a high-speed digital camera at 1000 frames per second. The initial droplet diameter was fixed at 3.1+0.1 mm

Collision Dynamics of A Liquid Fire Suppressant Upon A Heated Wax Surface

July 18, 2003
Author(s)
Samuel L. Manzello, Jiann C. Yang
The impact of a distilled water droplet upon a heated wax surface was investigated experimentally using a high-speed digital camera at 1000 frames/s. Two different droplet impact Weber numbers (We) were considered and the collision dynamics were
