Test of Detonation ZND Theory with Experimental Data of TNT

A two-phase repellent-translation equation of state of explosive detonation product (two-phase R-TEOS) was obtained. Using the two-phase R-TEOS and a known isentropic through the CJ point of an explosive as reference curve, the detonation parameters for various densities of the explosive can be estimated. The comparing the experiment data of detonation velocity for various initial density values of TNT which detonation product contains more solid carbon with the theory values estimated with above mentioned method, a new test of the hypotheses of the ZND theory was performed. The experiment and theory values of detonation velocity for various density values (from1.632 g/cm3to 0.901 g/cm3) are in good agreement, and their average relative difference is only 0.60%. The conclusion was drawn again that the hypotheses of the the ZND theory of detonation are true, and the two-phase R-TEOS is a proper equation of state of detonation product.
