Abstract
Pressure irregularities are shown to be present within the wave front in reacting nitromethane‐acetone solutions. Throughout the test series described, the reaction wave was overdriven, thereby producing reaction in solutions too dilute to detonate in a normal manner. This device served to produce large pressure irregularities which could easily be seen with our optical system. The irregularities in the more dilute nitromethane solutions are several millimeters in lateral extent although quite shallow normal to the wave front. High‐speed photographs are presented which show the irregularities to vary with the nitromethane dilution and with the strength of the initiating shock.
