摘要
The pressure-time evolution during the laminar deflagration of gaseous stoichiometric ethylene-air mixture in the presence of various inert additives is experimentally investigated in a spherical and two cylindrical vessels with central ignition, at initial pressures within 0.3-1.2 bar and ambient temperature (T(0) = 298 K).
The peak explosion pressures measured in the three closed vessels of different geometries are examined in comparison with the adiabatic explosion pressures, computed by assuming chemical equilibrium within the combustion products. These computations deliver also the adiabatic flame temperatures of isochoric combustion at various initial pressures. The influence of nature and amount of diluents on explosion pressure and flame temperature is examined together with the influence of initial pressure.
