The flow rate, surrounding condition and release duration were varied to study their influence on overall vapor cloud size i.e. diameter, height and explosive strength.
The high expansion foam firefighting process was studied with dynamic simulation of the foam action, and the characteristics of the foam action on the reduction of LNG vaporization rate, vapor cloud and flame size as well as the thermal radiation hazard were analyzed and discussed.
In the very rapid process such as the impact-induced vapor expansion, the size of the condensates is so small that the gas and condensates move together.
Besides the temperature being the most dominant process variable with regard to pyrolysis, other important factors include heating rate, feed-particle size, vapor residence time, and secondary reactions.
The tests were focused on the effect of gasoline vapor concentration and vent size on the pressure development and the flame behavior inside and outside the vessel.
After final drying (in a vacuum at 120 °C for 4 h) of the ceramics samples previously exposed to water vapor, the initial pore size tends to be restored (Table 2 and Fig. 3).
Both PCD-I and PCD-S powders were characterized, separately and mixed in variable ratios, based on dynamic water vapor sorption, SEM, particle size distribution, tapped density, compressibility, and flowability.
Using temperature and pressure sensors, this study revealed that the optimum value of working fluid filling ratios directly correlates to the pressure inside a heat pipe and the size of vapor space available.
