explo5 software EXPLO5 is thermochemical computer program that predicts the performance of ideal high explosives, propellants, and pyrotechnic mixtures on the basis of chemical formula, heat of formation, and density. As such, EXPLO5 is a useful tool in synthesis, formulation, and numerical modelling of energetic materials. EXPLO5 calculates equilibrium composition and thermodynamic properties of state of products species at a specified temperature and pressure applying the free energy minimisation techniques. These data, together with the Chapman-Jouguet detonation theory, enable calculation of detonation parameters such as detonation velocity, detonation pressure, detonation energy, etc. From the equilibrium composition and thermodynamic parameters of state along the isentropic expansion the program calculates the coefficients in Jones-Wilkins-Lee (JWL) equation of state by a JWL fitting program built in, and energy available for performing mechanical work. By combining thermodynamic properties of the products and conservation equations under constant pressure combustion conditions, the program predicts theoretical rocket performance (specific impulse, thrust coefficient, flow velocity, etc.), as well as the specific energy (or force, impetus) under constant volume combustion conditions. The program uses the Becker-Kistiakowsky-Wilson (BKW) equation of state for gaseous detonation products, the ideal gas and virial equations of state of gaseous combustion products, and the Murnaghan equation of states for condensed products. A variety of improvements have been done in the current version (Version V6.01) of the program: the program is now more robust, easier to use, has faster algorithms build in, possibility to treat different phases of the same product, has large database of reactants (more than 200) and products (more than 330), possibility to manipulate the database, customised the database access for multiple users on one computer, etc. However, probably the most important change is adding of new chemical elements that constitute reactants. The current version contain 25 elements: C, H, N, O, Al, Cl, Si, F, B, Ba, Ca, Na, P, Li, K, S, Mg, Mn, Zr, Mo, Cu, Fe, Ni, Pb, and Sb. This improvement makes EXPLO5 capable of predicting detonation and combustion performance of vide variety of high explosive, propellants, and pyrotechnic formulation. EXPLO5’s capabilities Detonation Calculation of equilibrium composition and thermodynamic parameters of state of detonation products along the shock adiabate, as well as the expansion isentrope of detonation products Calculation of the C-J point and detonation parameters (detonation pressure, velocity, temperature and heat, density of detonation products at the C-J point, etc.) Evaluation of the coefficients in JWL equation of state and calculation of the detonation energy applying the JWL model .Isobaric combustion (theoretical rocket performance) Isobaric combustion (theoretical rocket performance) Calculation of the equilibrium composition of combustion products, the adiabatic combustion temperature, and the heat of combustion Expansion of combustion products through the nozzle and calculation of theoretical rocket performance (e.g. pressure and flow velocity at the nozzle throat, exhaust and sound velocity at the nozzle exit, thrust coefficient, nozzle expansion ratio, specific impulse, etc.) Isochoric combustion (gun propellant performance) Calculation of the equilibrium composition of combustion products, the adiabatic combustion temperature, and the heat of combustion Calculation of pressure, covolume and compressibility factor of gaseous combustion products at a specified loading density Calculation of the force (energy) of energetic materials Database of reactants and products EXPLO5 comes with default database which includes around 200 of the most frequently used reactants and 330 products, as well as the covolumes and the constants in the BKW and the virial EOS for gaseous products, and the Murnaghan EOS for condensed products EXPLO5 enables the database access to be customised for multiple users on one computer. It means each user can use her/his own database and configuration files EXPLO5 can handle wide variety of different molecules and their mixtures (containing up to 25 different chemical elements: C, H, N, O, Al, Cl, Si, F, B, Ba, Ca, Na, P, Li, K, S, Mg, Mn, Zr, Mo, Cu, Fe, Ni, Pb, and Sb) Users can manipulate the database (add and remove compounds, modified data, and create user’s database file) EXPLO5’s graphical user interface Operation of EXPLO5 is simple and run starts with only one edit window. The easy and intuitive program operation can be viewed via screenshots of the EXPLO5’s Edit and the Preview/Start windows below. The progress of calculation can be followed from the Progress window. The most important calculation results are displayed in the Summary results window. A user can save detail calculation results in MS Excel file format (detonation run) or in Plain Text format (combustion runs). home about us contact us international representatives references news ntrem 2012 Miloslav Krupka OZM Research s.r.o.
