Investigation by means of CFD and small-scale laboratory experiments showed that flow bifurcations could occur in building spaces ventilated by buoyancy force with large opening ceiling.A theoretical model has been developed to determine the ceiling opening size at which the flow bifurcation occurs.The predictions were in good agreement with the experimental results obtained in this work.
