Abstract
Data on the most important combustion and detonation parameters, such as wave velocities, pressures and temperatures of products, specific energy release of mixtures are presented for saturated C n H2 n +2 (from methane ( n = 1) to eicosane ( n = 20)) and unsaturated C n H2 n (from ethylene ( n = 2) to eicosene ( n = 20)) hydrocarbons, methanol and ethanol as the main components of biofuels, and monofuels as a source of bifurcation structures of multifrontal detonation. Data are also given on on the critical initiation energies as a measure of the explosion hazard of combustible systems: the lower the energy, the more dangerous the mixture. Data were obtained for mixtures of each individual hydrocarbon with oxygen and air in a wide range of initial parameters: pressure, temperature, concentration and phase state of fuel components.
