The universal correlation for vented deflagrations in coordinates "dimensionless maximum explosion overpressure-turbulent venting parameter" was obtained for the first time in 1995 for 10 experiments and verified on 39 tests in 1997. To use universal correlation somebody needs to know the dependence of effective turbulence factor on explosion conditions. Equations for calculation of effective turbulence factor in dependence on main explosion conditions in hollow enclosure, i.e. volume and its vent ratio, are given for wide range of parameters, including volumes up to 4000 m³.
