Experimental and Numerical Simulation Study of Fuel-Air Mixture Explosion under Inert Condition

摘要：

The theoretical and experimental study of the explosive gas and mixture explosion process under inert condition in confined space is of great significance to explosion suppression technology. The turbulent combustion model controlled by chemical dynamics and turbulent mechanism under inert condition is established to describe the process of fuel-air explosion and combustion. On the basis of vector-splitting and reconstruction algorithm, the control equations are solved by finite volume method with TVD nature. The results show that the problem can be successfully solved by the model and the algorithm. The variable regularity of explosion development and key parameters under different conditions of inert is also obtained. The regularity got by the experiments is in good agreement with that by the numerical simulation, which further verifies the correctness of the numerical model and numerical method. The conclusions of experiments and simulation analysis can provide references for R & D of fuel-air inert explosion suppression technology. And the analysis models and methods can become effective means for research on the generation, development and propagation of explosion wave in confined space and inert gas explosion suppression.
