The main objective of the proposed PhD project is to evaluate and improve the capability of current CFD method in predicting flame spread behaviour of the high-rise building fires. This can be done by decomposing the issue into four main steps to be studied sequentially. These steps are

1. Under-ventilated enclosure fire
2. Façade fire ejected from enclosure
3. Flame spread and pyrolysis
4. Combustible façade fire
