Influence of Initial Pressure and Vessel’s Geometry on Deflagration of Stoichiometric Methane–Air Mixture in Small-Scale Closed Vessels

In the present work, experimental data on closed vessel explosions of stoichiometric methane–air mixture are reported for mixtures at ambient initial temperature and various initial pressures between 0.2 and 1.2 bar for small-scale closed vessels. The data are collected as pressure–time records in a spherical vessel and two cylindrical vessels with central ignition. The influence of initial pressure and vessel size and shape on maximum rates of...
