Аннотация:
This paper describes the results of measuring the temperatures of gaseous and liquid reacting media, which was carried out by the thermocouple method with the use of a battery (copper–Constantan–copper) of planar thermocouples, placed in the medium under study. It is shown that convective heat transfer lasting for 0.5–1.5 μs equalizes the temperatures of the “hot” thermocouple junctions and the environment. The relationship between the voltage occurring on the thermobattery during this heating and time was determined using a pulse oscilloscope. The measured maximum voltage was used to determine the temperature of the medium. A series of experiments was carried out on measuring the temperatures of water and emulsion explosive matrix, which were compressed by a shock wave, as well as the detonation products of ammonite with sodium hydrogen carbonate at various mass ratios. The estimates of heat fluxes from the detonation products to the metallic surfaces of the thermobattery contacting with them are obtained. © 2017, Pleiades Publishing, Ltd.
