摘要：
This paper is devoted to the study of flow distribution in dence city blocks. The up-to-date literature shows the lack of detailed evaluation of important factors for ventilation, wind pressure and wind velocity between buildings. Therefore, the ventilation designs have difficulty in caluculating airflow-rate accurately. In this study, these values and a new indicator, "Total pressure coefficient" are presented by wind tunnel tests and evaluated. Futhermore, correlation between Reynolds number and date obtained by wind tunnel test are presented to consider Reynolds number effect. © 2021 Architectural Institute of Japan. All rights reserved.
