Application of Heat Flux Microsensor in Radiation Measurement of Blasting Field

摘要

In order to investigate the thermal radiation effect of explosion field, the Heat Flux Microsensor was used in this paper. Through measuring the blasting heat effect of liquid-solid composite aluminized explosives，solid composite aluminized explosives，fuel-air explosives and TNT explosives with 27 kilograms respectively by the HFM, the corresponding dynamic curves were obtained. According to the HFM, the obvious signal of heat flux and thermal rise in blasting field are obtained; heat effect of blasting field is the result of the combination process of heat radiation and heat convection; the thermal damage of fuel-air explosive is 2.08 times bigger than TNT's based on the guide line of heat dose.
