- Abstract
- It has been extensively observed that pool fires form large scale structures which are shed at a characteristic frequency. Several attempts have been made to relate this pulsation frequency to fire dimensions and characteristics, such as the pool diameter and heat release. In the only theoretical work to date, Bejan bases his analysis on the buckling theory of inviscid streams, and predicts the vortex shedding frequency in good agreement with experimental results. The purpose of this study is to identify the characteristic frequency associated with the instability of a laminar thermal boundary layer occurring over a horizontal evaporating surface involving a chemical reaction, such as in the case of a pool fire.
