文摘

Modelling of release & dispersion for vertical impingement of propane jet. Comparison of Unified Dispersion Modelling (UDM) and advanced CFD modelling. CFD model predicts comparatively 2–3 times shorter distances to LFL/2. CFD model considers vertical impingement and additional time needed for full dispersion. The duration of the fire hazard is under predicted by UDM.
