These solutions are used to analyze the effect of the vertical location and the area of middle opening upon the thickness of smoke layer (stratification level) and the performance of natural ventilation. Three possible flow patterns in the building and two possible flow directions at the middle opening are first identified for all possible conditions in the building and the analysis is based on each condition. This paper focuses on the analysis of the smoke layer height in building fires. The performance of buoyancy-driven natural ventilation is also investigated. Interestingly, multiple solutions of the heights of smoke layers and the ventilation flow rates are found for a certain range of geometry parameters.
