Diffraction effects in weakly nonlinear detonation waves

In the limit of small heat release, large activation energy and weak nonlinearity, the propagation of detonation waves obeys a Geometrical Optics approximation. These equations develop caustic singularities, where the approximation fails. Here we present a derivation of a modified set of equations for weakly nonlinear detonation waves incorporating lateral diffraction effects. The modified set of equations does not fail at caustics.
