| 摘 要： | Aim To study fuel dispersion in fuel air explosive(FAE) andcomputational ways of fuel dispersion velocity in the near area. MethodsThe dispersion process of fuel in FAE was analyzed by the use of results measured withKODAK EKTAPRO EM Motion Analyzer and setting up mechanical models. ResultsComputational methods for fuel dispersion velocity in the acceleration stage is given andtaken as a base for the study of fuel dispersion in the intermediate and the far area. ConclusionWhen the fuel flow velocity is higher than that of the explosion gas in the center cavity,the fuel divides with the explosion gas and its velocity of flow reaches a maximum. Theacceleration stage ends at that time. The fuel dispersion velocity at this time is theinitial conditions for numeral analyses of dispersion process in the intermediate and farareas.
