| Abstract: | The process of liquid fuel explosive dispersal is simplified,and,in order to study the near field regin of the dispersal, a one dimension model of axial symmetrical gas flow is established.The numerical simulation is carried out by using a method of moving outer boundary.The spatial temporal distributions of important parameters in the near field process at different dose ratios are predicted by the numerical study.The computed results are in good agreement with the experimental measurements. |
