The study of the liquids and granular materials dispersed by high explosions is of great significance in the fuel‐air‐explosion and petrochemical fields. However, there is minimal dynamic dispersal research at high speed. Therefore, the numerical calculation methods of explosive dispersion have become a priority. A model is proposed that can predict the characteristics of the explosive dispersal for fuel both in the near‐field and the far‐field. Then, the basic laws of the fuel cloud formed during explosive dispersal are derived. The model is constructed by six parts of different processes, with the characteristics obtained by tracking the fuel droplets or particles and calculating their velocity, displacement, mass, and particle size. This model is validated using two sets of experimental data consisting of dynamic fuel dispersion and static fuel dispersion that fit the model well.

燃料云的全炸药弥散过程预测模型

高爆炸物散布的液体和颗粒物的研究在燃料－空气爆炸和石化领域具有重要意义。但是，很少有高速动态扩散研究。因此，炸药扩散的数值计算方法已成为当务之急。提出了一个可预测近场和远场燃料爆炸性扩散特性的模型。然后，推导了爆炸扩散过程中形成的燃料云的基本规律。该模型由六个不同过程的部分组成，其特征是通过跟踪燃料滴或颗粒并计算其速度，位移，质量和颗粒大小而获得的。
