The research on gaseous detonation has recently become a very important issue, mainly due to safety reasons in connexion with increasing importance of gaseous fuels. To simulate detonation, the Direct Monte-Carlo Simulation technique has been used. This technique is known to be a very powerful tool for solving complex flow problems. Simple model of molecular collisions, making it possible to increase the thermal energy of gas in a way similar to the processes in the flame has been proposed. This model is capable of producing waves, having the features characteristic for detonation waves. Finally the efficiencies of two known methods of extinguishing detonation: cooling the gas by cold channel walls and cooling by an expansion wave have been checked.
