flammable vapor cloud; deflagration; SIMPLE algorithm; numerical simulation

Combined with the improved Bakke-Hjertager combustion model the governing equations for flammable vapor deflagrations were established. SIMPLE algorithm was improved to be applicable to deflagration, which-was convergent in the simulation for the spherical and plane deflagration field. This paper proposes a grid plotting method. The space distributions of parameters such as velocity, temperature, overpressure and density were obtained. Compared to experimental results, the maximum deviation of calculated results is less than 12%.
