Summary
Ceiling jet beneath an unconfined ceiling above a steady fire, with the quantities used in the Alpert correlations. Based on Alpert (2002), pp. 2-18 to 2-19, and Iqbal and Salley (2004), p. 10-9.
Original illustration for Alpert correlations, level 4 Expert.
- Source basis: Alpert (2002), p. 2-18 (ceiling jet definition, entrainment at the lower boundary; Figure 2-2.1 on p. 2-18, redraw, do not copy) and p. 2-19 (turning region boundary at r/H = 0.18, H measured above the burning fuel); Iqbal and Salley (2004), p. 10-9 (jet depth 5 to 12% of H, maximum at about 1% of H) and Figure 10-3 on p. 10-11 (redraw, do not copy)
