At the customer's request, the formation and spreading of an explosive atmosphere and the optimal necessary explosion protection measures can be determined and analyzed using the most advanced software tools. In this case, mathematical equations describing physical processes are solved, and a 3D model (stationary or time dependent) or simulation is made, which can be used for analysis/determination of:

  • the size of explosion hazardous areas (zones),
  • the propagation of an explosive atmosphere in space and time,
  • appropriate local extraction and general room ventilation,
  • hot parts of the equipment which are not easily accessible with temperature sensors,
  • optimal micro-location of LEL detectors in the plant
  • inertization of the processing equipment,
  • the air flow profile inside a dryer (pockets of stationary or swirling air),
  • etc.

Because large computational power is usually required for 3D modeling and simulation, numerical calculations are performed on a supercomputer abroad.

Some examples from practice (click for larger view):

hazardous area - gas exhaust, dilution in the wind
(click on picture to rotate and magnify)

hazardous area - light gas exhaust, no wind, time slowed down

spreading of the flammable vapors - warehouse with natural ventilation (lower outlet opening), open container with volatile flammable liquid, time is accelerated

heat transfer - heat is transferred from the heating element to the metal structure, colors show temperature change, time is accelerated

air velocity profile inside a dryer - air inlet on top, outlet bottom left. Bottom right swirling air pocket. Bottom picture shows the effect of additional barrier near the outlet
