Abstract: In this study, a combined simulation and experimental method is suggested to determine the heat flow rate produced by detonation products with a planar thermocouple battery placed inside the test medium. A series of experiments was conducted to measure the temperature of products produced by the detonation of ammonite mixed with quartz sand, sodium bicarbonate, and talc over a detonation velocity range of 2–2.8 km/s. By solving the inverse heat conduction problem, we can obtain a time dependent relation for heat transfer from the detonation products to the flyer plate. It is shown that the temperature of the detonation products in the mixtures and the maximum heat flow to the flyer plate rise with an increase in the detonation rate. A quantitative evaluation of heat transfer to the flyer plate by the explosive detonation products is conducted. It is demonstrated that when thin plates (foils) are used as flyer plates, a preheating of the contact area of the colliding components occurs.
