Constant volume explosion of organic dust - air mixture at microgravity and normal gravity

Comparative studies of the dust explosion process at normal gravity and microgravity conditions for different kinds of dust , different dust concentrations and different levels of dispersion turbulence are presented. The research was carried out in the 13.5 dm3 cylindrical combustion chamber with L/D=1. Microgravity experiments were conducted in the drop tower. Influence of the initial turbulence as well as natural convection on the dust explosion development was determined.
