Chapter 5: Correlation of Obstructed Plume Models with Heskestad Plume Predictions
The Heskestad plume correlation is typically used for unobstructed plume simulations and modified to account for changes in plume temperature due to an obstruction. This modification is estimated through a comparison of the results of fire model simulations against the existing Heskestad plume correlation. The software used to simulate and estimate fire plume temperatures subject to obstructions in this study is FDS Version 6.0.1.
RACHELLE-Fire presents methodology to correct for the ZOI due to the obstructed plume effect encountered in electrical enclosures.
