Effect of flame zone depth on the correlation of flame length with fireline intensity
International Journal of Wildland Fire, 2023 Background Previously established correlations of flame length L with fireline intensity IB are based on theory and data which showed that flame zone depth D of a line fire could be neglected if L was much greater than D.

Prediction of Flame Length of Horizontal Hydrogen Jet Fire during High-pressure Leakage Process
, 2018 In recent years, jet fire accidents caused by gas tank or pipe leakage are often reported to cause more serious losses and even induce a series of other accidents, especially for high pressure jet fires.
