英文摘要 | The formulae of stability criterion in the explosives' thermal decomposition reaction were developed from both of their transient mass and heat transfer balance equations simultaneously. The final obtained equation for the sufficient and necessary conditions of explosives' stability is expressed the modified Sermenov's number Φ as: Φ<1/(1-x)n exp{θ/βθ+1} {1/(βθ+1)2-n/η(1-x)} The modified Sermenov's numberΦ in this term is expressed function of three kinetic parameters, i.e., n, ηand β and two variables, i.e., x and θ, respectively. An explosive's reaction is stable if its evaluated modified Sermenov's number is satisfied this stability criterion. Four explosives, i.e., TNT, RDX, PETN and HMX were used for the calculations of Φ’ s variations. The values of n, ηand β in these energetic materials' were evaluated from literatures' experimental data. Then, the values of <Φwhich were expressed as function of θ and x in three dimension plots. |
