Model & approach
- Represent the bunker, material fill, release source and ventilation paths in one species-transport model
- Compare regular, reduced and additional extraction through control volumes and selected monitoring points
Project study
Safety assessment of bunker ventilation during gas release
A separate CFD study assessed dilution and removal of a released gas in an industrial bunker across regular and additional ventilation states.
Engineering question
Ventilation capacity and opening arrangement had to be assessed across different fill and disturbed states so local accumulation regions remained identifiable.
Boundary conditions
- Time-dependent gas dilution in a large process enclosure
- Several fill, opening and ventilation states
Results of the assessment
- The assessment separated the effect of general air exchange from local capture and additional extraction.
- Fill state and opening geometry governed where slowly ventilated regions developed.
Engineering consequence
The results supported ventilation-concept development and prioritization of local monitoring regions.
