摘要
The "chained analysis of wind tunnel test and CFD (computational fluid dynamics)" for cross ventilation of a large indoor space is proposed and an analysis example for a large-scale wholesale market building is demonstrated. The procedure of the "chained analysis" is as follows. With a wind tunnel model experiment, the overall airflow rate of cross ventilation and the wind pressure distribution at the building openings are measured. CFD simulation for the indoor how field is then carried out with the boundary conditions of the measured wind pressure distribution. The simulated overall airflow rate of cross ventilation is then compared with that obtained from the wind tunnel test and the reliability of the CFD is confirmed. Detailed analysis of contaminant distribution in space is conducted with the obtained flow field From CFD simulation. With this procedure, reliable and detailed analyses of cross-ventilation characteristics of large indoor spaces become possible. To demonstrate the above-mentioned procedure, cross ventilation of a large-scale wholesale market building was analyzed and ventilation efficiency in the indoor space was evaluated.
