Stagnation Pressure of Imploding Hollow Shells

Movie:

Our motivation for employing this model is that the shell compression at the time of stagnation (t=0) in realistic capsule implosions -- as they would typically occur in inertial confinement fusion capsules -- can be modeled surprisingly accurate by the self-similar description. This leads to a scaling law for the ignition energy of ICF capsules which corresponds quite well to numerical simulations of capsule implosions.
