Model & approach
- Represent fill states, supply air, extraction and a local release in a three-dimensional flow model
- Compare normal operation, disturbed ventilation and additional extraction at consistent evaluation locations
Project study
Gas dispersion and emergency ventilation in a process bunker
Flow simulations assessed air routing, gas transport and the effect of regular and additional extraction paths inside a partially filled process enclosure.
Engineering question
Uneven throughflow could favour local gas accumulation, requiring ventilation, partitions and monitoring locations to be assessed as one system.
Boundary conditions
- Steady flow states and time-dependent species transport
- Several fill states with regular and additional extraction paths
Results of the assessment
- The baseline arrangement did not provide uniform longitudinal throughflow in every region.
- Source-near extraction, additional openings and revised partition geometry were the principal design levers.
Engineering consequence
The variant assessment supported placement of supply and extract paths and the selection of meaningful monitoring locations.
