Dust cloud evolution and flame propagation of organic dust deflagration under low wall influence

The present study discusses experiments on organic dust explosions in a setup with low wall influence. proposed apparatus decouples the dispersion and deflagration event two separate compartments. use of continuous-wave laser to illuminate centre plane observation chamber allows capturing both, cloud flame during same experiment eliminates typical problems caused by limited dynamic range high-speed cameras. A k-means clustering method is used for image segmentation obtain spatial extent propagation velocities unreacted particle zone. Spatially resolved are calculated additional an optical flow method. main goal presented processing provide high quality validation data development numerical models deflagration.
