| Abstract |
In this paper, the analysis of TNT equivalent method for practical mixture gas explosion was performed to simplify the gas explosion analysis. Autodyn which was specialized for analysis of explosion and impact was used to simulate the behavior of structural element. By using linear elastic material properties, we can see general displacement behavior aspect and consider various natural periods of structural element. After comparing model of mixture gas property with TNT equivalent model in terms of the maximum displacement of structural elements, we proposed optimized TNT equivalent analysis method for practical mixture gas explosion by using proper explosion efficiency. The mixture gas properties was obtained from C.E.A program which can calculate chemical equilibrium product concentration from any set of reactants and determines thermodynamic and transport properties for the product mixture. |
