Study on Thermal Damage of Thermobaric Explosive

Using the infrared thermal image instrument,the blasting fireball′s temperature of thermobaric explosive with different mass and TNT were measured.According to the experimental data,the temperature filed of the two kinds of explosives were analyzed and the relation of diameter and duration of fireball to explosive mass were simulated.Thermal damage rule was confirmed with blasting characteristics of thermaobaric explosive,and combined with Baker′s fireball model,thermal damage radius in different degree of thermobaric explosive and TNT were calculated.Results indicate that thermobaric explosive possess good thermal damage effect and the equivalence of TNT for thermobaric explosive obtained by action area evaluation reach 3.89.
