Abstract
The fire whirl occurring in the urban and/or wildland fire is generated by the instabilities of atmosphere. The fire whirl is a rare phenomenon, but highly destructive because it has high inhalation and lift force. In this study, experimental and numerical studies are performed with oriental oak leaves, for investigating of the fire whirl characteristics occurred in wildland fire. As a result of experiment, the circulation intensity increases as the induced air speed increases, then the heat release rate and flame height increase 22.8%, 18.4% compared with open fire in highest circulation. Furthermore the numerical results shows same trend with the experiment.
