    • Abstract
  • The RNG κ-ε turbulent flow model based on the total energy equation and the step-by-step reaction gas explosion combustion model based on variety of control mechanisms are established,in which finite volume method is applied to get explosion flow and reaction control equation.The flow field characteristics of the parameters in explosion processes were showed clearly.And the developments and changes of the explosion pressure,the flame temperature,the change of gas components were analyzed in the processes of different explosion conditions and the different times.And the corresponding variations were obtained.
