Abstract
In the frame of industrial risk and propulsive application, the detonability study of JP10–air mixtures was performed. The simulation and measurements of detonation parameters were performed for THDCPD-exo/air mixtures at various initial pressure (1 bar < P 0 < 3 bar) and equivalence ratio (0.8 < Φ < 1.6) in a heated tube (T 0 ~ 375 K). Numerical simulations of the detonation were performed with the STANJAN code and a detailed kinetic scheme of the combustion of THDCPD. The experimental study deals with the measurements of detonation velocity and cell size λ. The measured velocity is in a good agreement with the calculated theoretical values. The cell size measurements show a minimum value for Φ ~ 1.2 at every level of initial pressure studied and the calculated induction length L i corresponds to cell size value with a coefficient k = λ/L i = 24 at P 0 = 1 bar. Based on the comparison between the results obtained during this study and those available in the literature on the critical initiation energy E c, critical tube diameter d c and deflagration to detonation transition length L DDT, we can conclude that the detonability of THDCPD–air mixtures corresponds to that of hydrocarbon–air mixtures.
