摘　　要：本文建立了含能材料密实床燃烧转爆轰的全粘性欧拉二维非定常两相反应流数学模型。将SIMPLE型的数值计算方法引入燃烧转爆轰的二维数值计算。对跨音速流动的处理和可压缩流体压力校正方程的建立提出了改进方法,并以无起爆药雷管作为算例。结果表明,本方法较好克服了二维两相流数值解的振荡现象。The numerical modeling of Eularian two-dimensional unsteady two-phase fully-viscous reactive flow for deflagration-to-detonation transition (DDT) processes of energetic materials in high-loading beds is investigated. The improved SIMPLE methods are successfully utilized for two-dimensional numerical calculation of the DDT. Special treatment for transonic flow and derivation of the pressure-correction equation for compressible fluid are presented. As an example, the calculated results for non-primary-explosive detonator show that this method weakens the numerical oscillation of 2D-two-phase flow more effectively.
