               Abstract:  In order to investigate the coupled enhancement effects of shock wave and temperature generated by thermobaric
               explosives in confined spaces, internal explosion experiments were conducted with 100−400 g charges in a confined building
               space. Pressure sensors and thermocouples were employed to obtain the explosion pressure and temperature data at different
               locations within the confined space. The experiments revealed the evolution characteristics and propagation patterns of the
               shock wave and temperature field produced by the thermobaric explosive. The results show that the temperature generated by
               the  internal  explosion  of  the  thermobaric  explosive  exhibits  significant  secondary  heating  and  prolonged  duration
               characteristics.  A  decay  model  for  the  initial  peak  temperature  based  on  the  scaled  distance  was  established.  The  TNT
               equivalence  coefficient  of  the  shock  wave  from  the  internal  explosion  of  the  thermobaric  explosive  exhibits  a  concave
