Life cycle assessment (LCA) of hydrogen production from underground coal gasification (UCG) with carbon capture and sequestration (CCSA)
Download2015-01-01
Western Canada is endowed with considerable reserves of deep un-mineable coal, which can be converted to syngas by means of a gasification process called underground coal gasification (UCG). The syngas can be transformed into hydrogen (H2) through commercially available technologies employed in...

Dynamic Fragmentation of Natural Ceramic Tiles: Ejecta Measurements and Kinetic Consequences
Download2013
Vincent, Gregory, Rogers, Robert, Spray, John, Schneider, Markus, Hogan, James
Velocity and size measurements of ejecta derived from impacts of railgun-launched projectiles into 10 mm thick gabbro tiles are examined. Fragmentation of the target and the ejecta velocity field are found to be governed by Hertzian fracture and the transfer of kinetic energy to the target. Over...

Debris Field Kinetics during the Dynamic Fragmentation of Polyphase Natural Ceramic Blocks: Ejecta Measurements and Damage Modes
Download2013
Hogan, James, Schneider, Markus, Rogers, Robert, Spray, John, Vincent, Gregory
The dynamic fragmentation of coarse and fine grained granitoid blocks during impact has been examined for energies of 1.9 kJ to 3.0 kJ and 2.7 kJ to 6.8 kJ, respectively. A particle tracking algorithm was developed to measure ejecta size and velocity at the rear of the target for a horizontal...

Impact Failure of Planetary Materials: Lateral Field Ejecta Measurements using Particle Image Velocimetry
Download2014
Schneider, Markus, Spray, John, Rogers, Robert, Hogan, James, Vincent, Gregory
The dynamic fragmentation of a fine grained granitoid material has been examined. Target thicknesses ranged from 7 to 40 mm and impact energies from 12 to 2,500 J. Combined particle image velocimetry and image enhancement techniques are introduced and have been used to measure the size and...
