Engineering question

Uneven throughflow could favour local gas accumulation, requiring ventilation, partitions and monitoring locations to be assessed as one system.

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

Boundary conditions

  • Steady flow states and time-dependent species transport
  • Customer-independent consolidation of closely related bunker and ventilation assignments

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.
