Smouldering is a slow and low-temperature form of combustion,which shows no flame. Smouldering is a serious hazard because of its low ignition temperature, which makes it particularly relevant to fire initiation and spread, and as well as its toxic emissions. Smouldering plays a vitalrole in bushfires, as many forest biomass fuels such as grass, leaves andcoarse woody debris are prone to smoulder. However, smouldering hasbeen scarcely investigated from the point of view of bushfires. Hence, theproject aims to develop a greater understanding of the initiation of smouldering combustion under different conditions with emphasis on bushfires. 

The research questions are

1. What are the key smouldering combustion regimes and what are the key parameters to identify each regime?

2. What are the effects of heating rate on the initiation of smouldering combustion?

3. What are the effects of oxygen concentration on the initiation of smouldering combustion?

4. What are the effects of heat transfer mechanism on the initiation of smouldering combustion?

5. What are the effects of fuel type and properties, such as average particle size, layer depth and moisture content on the initiation of smouldering combustion?
