Shock-induced cavity collapse has been identified as an important ignition mechanism in condensed phase explosives. To this end, we perform numerical simulations of resolved cavity collapse in reacting liquid nitromethane. It is observed that the collapse generates peaks of temperature in front and behind the point of collapse as well as in regions where strong shock waves overlap. The temperature field is analysed and conclusions on the mechanisms of hot spot generation are drawn.
