Flame propagation in dust clouds. Numerical simulation and experimental investigation

Figure 2.6 (a and b) shows a picture of the pipes as installed in the channel. In both cases, the obstacles were placed in the fuel chamber region, which means that they also have

The negative sign indicates that the particles were negatively charged, the positive current seen in the ECOMA dust data above 95 km is not an indication of positively charged

Figure 2.1: The projectile is modelled using a finite element mesh, whereas the target is modelled as a stress boundary condition applied to the projectile surface elements.. 2.2

gradient. Moreover Appendix D shows that the distances for the gradients in each point can be different depending on how steep the gradients in the [\ and 45 ° -direction are.

The SPH technique and the corpuscular technique are superior to the Eulerian technique and the Lagrangian technique (with erosion) when it is applied to materials that have fluid

The wave generation and propagation of steep irregular waves in the numerical model is validated by comparing the numerical wave spectrum with the experimental input wave spectrum..

 Combustion rates are considerably lower than those shown for gas explosions, with an exception for rich gaseous mixtures, confirming earlier observations for laminar

This thesis describes an experimental investigation of flame propagation in a 3.6-meter Flame Acceleration Tube (FAT) by the use of optical probes for flame detection and
