文摘

The maximum (peak) pressures, maximum rates of pressure rise, times to reach the peak pressure, and severity factors, representing the most frequently used pressure-related phenomenological parameters for risk assessment connected with laminar deflagrations, are measured and reported for various ethane鈥揳ir mixtures (3.42鈥?.58 vol %) at different initial pressures (30鈥?30 kPa) and temperatures (298鈥?23 K). The reported results are obtained from the pressure鈥搕ime records during the laminar deflagration in a 0.52 L spherical vessel with central ignition and are compared to the available literature data. Their magnitudes and dependencies upon operational parameters are given and discussed on the basis of simple theoretical models.
