Experimental Study on Explosive Thermal Effect of the Non-ideal Explosive

The WRe5/26 thermocouple made by ourselves was taken as the analogue which was analyzed by heat transfer theory.The thermal effects of some kinds of thermo-baric explosives were tested by contact thermometry.The results show that the thermocouple could satisfy the experiment requirement.The analogue′s thermal response temperature synchronously related to the detonation product′s temperature and the convection coefficient.The analogue′s surface temperature could approach the detonation product′s temperature quickly along with the convection coefficient increase.The thermal effect declined basically as sigmoid shape with the distance between the analogue and explosion centre.The heat flux density was about 106W/m2 in vicinity.
