DISPLAY
Intermingled fragments of burned and unburned combustible gas are
set in relative motion by a shock wave. The increased entrainment
rate leads to further chemical reaction, which, depending on the
presumptions made for fragment size and reactivity, may lead to
detonation. The following cases provide a parametric study of the
influences of the interfluid friction factor (which increases as
fragment size diminishes) and the inter-fluid entrainment factor
(which is expected to be of the order of 1.0).
PHOTON commands are provided to facilitate display.
