Influence of Initial Temperature on Explosion Severity Parameters of Methanol/Air Hybrid Mixture Measured in 1-m³ Vessel

Abstract

The maximum explosion pressure (Pmax), the deflagration index (KG) and the explosion duration (tex) have been determined in spherical explosion vessel (1 m3) for various methanol/air mixtures concentrations (6.0-25.0 vol. %) at ambient initial pressure (101 kPa) and three initial temperatures (25 °C, 50 °C, 100 °C). The outcome of this preliminary study is to quantify the dependency of explosion parameters on two variables - methanol concentration (C) and initial temperature (T0), respectively.
