Abstract.
A detailed kinetic model devoted to the hydrazine vapor detonation has been built. It consists of 33 reversible reactions and 13 species. A reduced kinetic model has been proposed by using the Principal Component Analysis of matrix F (PCAF) method as implemented in KINALC. It is constituted of 26 reactions and 11 species. This model has been shown to be valid over a pressure range of 0.1 to 10 atm. However, the predictions of the models are significantly affected by changes in the enthalpy of formation of N\(_2\)H\(_3\). With the help of the full kinetic model, a value of A, the proportionality factor in the ZND model between the induction distance in the detonation wave and the detonation cell size, of \(27.5 \pm 3.0\) has been derived if one considers that the collision efficiency of N\(_2\)H\(_4\) on the thermal decomposition of hydrazine is equal to the one of N\(_2\). The value of A for pure hydrazine detonation is shown to be strongly dependent on the value of the collision efficiency of N\(_2\)H\(_4\).
