Abstract

In this artical, firstly, estimation method of flame combustion regime of the oil-gas explosion was discussed and three oil-gas explosion experiments under the conditions of low, middle and high initial gas vapor concentration were carried out, and then the Damköhler number and the turbulent Reynolds number for the early, interim and late stage of the oil-gas explosion at low, middle and high initial gas vapor concentration conditions were calculated according to the experimental data. Finally, through the Damköhler number vs. Reynolds number diagram, the combustion regimes for each stage of the oil-gas explosion at low, middle and high initial gas vapor concentration conditions were quantitative estimated. Results show that the combustions at early, interim and late stage of the gas-air explosion under the conditions of low, middle and high initial gas vapor concentration in the tube have the same regime of flameletes-in-eddies. The conclusions of this paper can provide some useful reference for the further study of combustion regime and the numerical analysis model selection of the gas-oil explosion.
