| Abstract: | Based on the theory of reaction fluid dynamic, numerical simulate about the process that shock waves induce the combustible gas deflagrating in one-dimensional system with the chemical model of nine equation is successfully accomplished. The generation mechanism of the induced process and an important effect of shock waves extinguishing the forest fire are clearly interpreted by the density variety of CO and the variety of pressure and temperature in the field. |
