The Theory Calculation Of Detonation Parameters For Industrial Explosive

Investigation on detonation parameter of commercial explosives and quantificational characterization of detonation is of considerable significance in formation of new commercial explosives, blasting application, and improvement of blasting effects. In this paper, mass-momentum-energy equations under one-dimensional Chapman-Jouguet(C-J) hypothesis and Abel Covolume equation of state (EOS) is adopted to structure model of mathematics. The detonation parameters of commercial explosives was calculated and compared results with experimental datum. The primary research works and conclusion is following.Based on the hydrodynamic theory of detonation and the Gibbs free energy minimization principle, the detonation parameters of the industrial explosives was calculated .This paper attempts to use of the Abel Covolume equation of state. According to the literature, a table comparing the theoretical value with experimental datum by Cooke, we can see that the amended the Abel Covolume equation of state has a very good match at a range ofρ=0. 85g/cm3~ρ=3 g/cm3[1] . In the daily works , we used of the industrial explosives density falls within the scope of this one. Therefore , adopting the Abel Covolume equation to calculate the detonation parameter of commercial explosives is feasibility of state theoretically.we need to receive numerical value of the balanceable system of detonation products. When we want to Calculate the detonation parameters of industrial explosives, However, receiving numerical value of the balanceable system is a complex process. Therefore, we require the computer to calculate the program. In order to satisfy the requirements to simple program and the accurate result, this paper select the advanced object-oriented programming language that the Microsoft Visual Basic 6.0 to frame.This author calculated the numerical value of the balanceable system of detonation products of two kind of gases explosives and eight kind of the agglomerate explosives Analyzing the results of calculated and Comparing of calculated results with experimental value and literature's value, The compare indicate that the calculated results is fit to the experimental value and literature's value.Thus proved the Abel Covolume equation of state applicable to the calculation of commercial explosives's detonation parameters, and the program of this paper has a accuracy and reasonable data .
