Abstract

This project’s aim is to understand the formation or phenomenon of fire whirls and investigate critical parameters such as distance between main flames and surrounding fires, and air stream velocity, which contributes towards the formation of intense fire whirls. Fire fire interactions occurs naturally when spot fires start ahead of the main fire and seperate fire events converge in one location. Understanding and predicting the changes in behaviour of fire whirls due to fire-fire interactions cannot only be life-saving to those on the ground, but also be used to better control a prescribed fire to meet objectives. A fire whirl can cause devastating damage in an open space, as it is experienced in bushfires, and wildland fires. Small scale laboratory experiment was conducted to figure out the occurring of fire tornados due to fire-fire interactions and find critical distance, and indraft wind velocity which cause fire whirls. The optimum gap width (D), gap fraction (nn) and critical wind velocity (V) which is responsible for the formation of fire whirl and is validated from data recorded during experimental phase. Finally, data obtained provides evidence that fire whirl caused by optimum distance between side flames and main flames, and inward airstream speed.
