Abstract

TheexplosionfireballsdescriptiveparametersofathermobaricexplosiveandTNT were measuredbyaninfraredimager.Accordingtotheexperimentdata,adynamicmodeloffireballthermalradiationwasstudied, andthechangeofthefireballssizeandpositionwasquantitativelydescribed. Basedonthedynamicmodel,thethermaldamagesofthethermobaricexplosiveandTNT fireballswereanalyzed.Theresultsshowthatthethermaldoseofthethermobaricexplosiveis3.6- 4.8timesasmuchasthatofTNT,whichindicatesthatthethermobaricexplosivehasadvantagesin thethermaldamageeffect.Comparedwithastaticmodel,thedynamicmodelismorereasonableto estimatethethermaleffectofexplosive-fireball,sinceitcandescribethemovementoffireball
