Correlations for Fire Plumes

摘要

This study began as a review of data and correlations for line plumes. In itsattempt to develop a consistent set of correlations for that data set, it developed an analysis to account for the base geometry of the fuel source. Although point source models were used, the diameter or rectangular source dimensions were included in improved solutions for flame height and entrainment rate. The analysis also explicitly includes the effect of flame radiation. Theoretically developed equations for near field entrainment and flame height with empirical lead coefficients were found to fit a wide range of data including fuel base diameters of up to 0.5m. results are also presented for rectangular fires, and the theoretical basis for the correlation developed unifies data over a wide range of base dimensions ranging from a square to a line.
