Flames, Shocks, and Detonations: Understanding Explosions in Tubes

Carlton Cross

Jason Damazo

Sometimes explosions happen. When they do, surrounding things can break--important things like nuclear processing facilities. To prevent disaster, we need to understand just how badly explosions can damage structures. To this end we'll use laboratory experiments to explore supersonic gaseous combustion waves called detonations, and will investigate how explosions effect destruction so that said destruction can be prevented. Nanosecond-speed schlieren photos will be presented to show how detonations actually behave.

Jason Damazo always liked math, but it was the kindness and openness of the Walla Walla mathematics department that convinced him to be a math major (in addition to mechanical engineering). After leaving Walla Walla, Jason accepted Guggenheim and NDSEG fellowships to study combustion at the California Institute of Technology in Pasadena. Jason convinced Caltech to let him play with lasers, flammable gases, and half-million dollar cameras all in the same room. To prevent any further damage, Caltech will be awarding him a PhD in Aeronautics in May--at least assuming his thesis defense is successful. Afterwards, he'll be returning to Washington as a Shock Physicist for Boeing.

When he's not studying or blowing things up, he ;ikes to run, cook, and play board games; but not usually at the same time.

Note: due to transportation difficulties, Jason Damazo was not able to attend the conference. Ross Magi graciously agreed to give a presentation in his place.
