A00.00001: Calculating Overdriven Detonation for Reaction Product Shock States for Pressures Higher than those for Steady Detonation Waves Invited Speaker: Craig M Tarver When detonation waves impact high impedance materials, are overdriven in gas gun or laser experiments, enter a converging geometry, etc., shock pressures much higher than steady, Chapman-Jouguet (C-J) detonation can be generated. Such measurements have steadily improved over the past 50 years as spacial and time resolution have improved. 1 So has reaction product equation of state modeling. The Jones-Wilkins-Lee (JWL) reaction product equations of state were originally fit only to product expansion below C-J and were too compressible at higher pressures. Urtiew and Hayes 2 showed that by raising R 1 , R 2 , and ω, they could improve fits to overdriven data, while still matching product expansion data below the C-J state. |
