The total amount of silicone oil is 200 kg. Droplets of constant diameter are injected in different directions over a course of 4 s with a prescribed velocity. Ignition of the droplets is achieved by setting a high temperature in the surrounding surfaces for a short period of time period (0.3 s). The video shows the heat release per unit volume (200 kW/m3) and the soot. The computational domain has dimensions of 160 m x 160 m x 160 m. The resulting maximum diameter of the silicone oil fireball is on the order of 80 m.
The total amount of silicone oil is 100 kg. Droplets of constant diameter are injected in different directions over a course of 4 s with a prescribed velocity. Ignition of the droplets is achieved by setting a high temperature in the surrounding surfaces for a short period of time period (0.3 s). The video shows the 3D smoke - temperature. The computational domain has dimensions of 160 m x 160 m x 160 m. The resulting maximum diameter of the silicone oil fireball is on the order of 50 m.
The total amount of silicone oil is 200 kg. Very coarse droplets of constant diameter (4000 microns) are injected in different directions over a course of 4 s with a prescribed high velocity. Ignition of the droplets is achieved by setting a high temperature in the surrounding surfaces for a short period of time period (0.3 s). The video shows the 3D smoke - temperature. The computational domain has dimensions of 160 m x 160 m x 160 m. The resulting maximum diameter of the silicone oil fireball is on the order of more than 80 m.
The total amount of silicone oil is 200 kg. Coarse droplets of constant diameter (2000 microns) are injected in different directions over a course of 5 s with a prescribed high velocity. Ignition of the droplets is achieved by setting a high temperature in the surrounding surfaces for a short period of time period (0.1 s). The video shows the 3D smoke - temperature. The computational domain has dimensions of 200 m x 200 m x 150 m.
The total amount of silicone oil is 250 kg. Coarse droplets of constant diameter (2000 microns) are injected in five different directions over a course of 5 s with a prescribed velocity (on the order of 30 m/s). Ignition of the droplets is achieved by setting a high temperature (10000 C) in a surrounding surface for a short period of time period (0.2 s) essentially trying to emulate an electric arc event. The AIT of silicone oil is set to 350 C. The video shows the 3D smoke - HRRPUV. The computational domain has dimensions of 200 m x 200 m x 200 m.
