抄録
The conventional method to predict flow rate of a room cannot work well for cross-ventilation through large openings, and predicted flow rate becomes smaller than actual one. As a final goal of the work, the authors aim to establish an improved prediction method based on mechanical energy balance inside stream tubes passing around/through a building, i.e., power balance model. Since the cross-ventilation is quite complicated flow phenomenon, a detail of the flow characteristics in flow paths inside/outside the building has not been sufficiently clarified. This paper first presents discrepancy in flow rate between conventional prediction method and actual one by means of wind tunnel experiment. Afterwards, variation in flow quantities inside flow path through a cross-ventilated room is shown in accordance with opening size to understand the phenomenon. Finally, to validate CFD analysis which is essential to analyse the stream tube in the future work, its accuracy is to be shown by comparing experimental and numerical results for the flow path passing through a simplified building model.
