Study on electrical conductivity of detonation products of aluminized explosives

Abstract Using the thermodynamic equilibrium constant method and JWL-Miller equation of state, based on calculation parameters such as composition, pressure, explosion temperature detonation products aluminized explosives in Magnetocumulative generator, Saha ionization equation, gas conductivity model are used to write Matlab code calculate electron density magnetic flux compression generator. The temporal spatial variation law is revealed. simulation shows that thickness maximum layer process about 1 mm moves at a uniform speed following CJ surface.
