A small amount of flammable gas mixed with dust can cause a large explosion with serious consequences. In this study, explosion tests of hybrid mixtures were performed in an explosion chamber with a volume of 0.02 m3. Spitzer et al. (2023) presented the first ever test of hybrid mixtures with methane as the gas component and a specific cornstarch as the dust sample, investigating the practicality of the whole procedure, the dispersion of the results and the variation between the test apparatuses. The research ment...

A small amount of flammable gas mixed with dust can cause a large explosion with serious consequences. In this study, explosions of hybrid mixtures will be performed in an explosion chamber with a volume of 0.02 m3 and 1.00 m3. Research into testing the explosion characteristics of hybrid mixtures is usually conducted under standard conditions. Testing the explosion characteristics of hybrid mixtures at higher initial temperatures has already been presented in several earlier studies. Hybrid mixtures are created a...
