Indoor Dispersion of Gases, Droplets or Particulates
Events such as the sarin attack on the Tokyo subway and the anthrax attacks via the postal system in the United States have focused attention on terrorist threats in confined spaces. Accurately predicting the spread of dangerous substances is important in preparing for possible attacks and in understanding an attack that has taken place.
Fluent's valuable experience with indoor dispersion applications can help you analyze the:
- Spread of smoke during indoor fires in places such as airports, sports arenas and tunnels
- Design of fume hoods
- Ventilation of parking garages and ferryboat car decks to minimize exposure to carbon monoxide
- Avoidance of toxic gas pockets in confined spaces
Fluent also has experience with projects that focus on predicting the:
- Spread of biological agents in subway stations to find the optimum placement of sensors
- Spread of smoke during subway fires
- Effectiveness of airliner fuel tank inerting. This consists of pumping nitrogen-enriched air into the fuel tank in order to reduce the oxygen concentration.
- Spread of viruses in jetliner cabins
