A simplified model for room cross-ventilation airflow has been developed using scaling analysis,experimental correlations and computational fluid dynamics. The model considers the main jet region and the recirculations region and leads to a set of formulas that predict the airflow rates and characteristic velocities in these two regions. Examples of application of the model to cross-ventilation design are presented.
