"Understanding Explosions: From Catastrophic Accidents to the Creation of the Universe"
Elaine Oran, Senior Scientist for Reactive Flow Physics at the Naval Research Laboratory, will speak about scenarios that range from the Big Bang, to thermonuclear explosions in stars, to magnetohydrodynamic explosions in the sun, and to most of the chemical explosions on earth. In each case, the explosion event is short and dramatic, and it is usually with excitement and alarm that we see, hear, or feel the effects. In this presentation, we examine some of the fundamental fluid and chemical properties and transitions that are the underpinnings of all explosions. We consider how the transitions that occur on the smallest scales can have catastrophic large-scale effects.
