Each vent process is initiated at 140 kPa and ended at 120 kPa with liquid nitrogen fill levels which are 30%, 50 % and 70, respectively.
This study of the three-dimensional stratigraphy and facies architecture across the Orion Central kimberlite volcanic complex highlights the variations in upper and extra-vent processes.
Three types of venting processes were concluded in the experiments: no secondary flame and no secondary explosion, secondary flame, secondary explosion.

The flame appeared as the normal constant-pressure combustion when the pressure venting process finished.
"I'm sure it will be a venting process as well because people are very upset," he said.
During this venting process, there is still too much pressure for a person to consider other perspectives.
The study is significant to reveal the essential characteristic of explosion venting process and improve basic theory of gas explosion venting.
An isothermal transport model has been developed to predict the spatially and temporally varying composition of the liquid mixture within the contaminated region during the venting process.
The experiments demonstrated that it is possible to generate overpressures greater than 200 mbar with volume blockages of as little as 0.57%, if there is not sufficient outflow through the inadvertent venting process.
The results indicated that the flame appeared as the under-expanded free jet with shock diamonds, when the overpressure in the chamber was larger than the critical pressure during the venting process.
