Evaluating single-sided natural ventilation models against full-scale idealised measurements: impact of wind direction and turbulence [PDF]

, 2020
Commonly single-sided natural ventilation is used in temperate climates to provide comfortable and healthy indoor environments. However, within built-up areas it is difficult to predict natural ventilation rates for buildings as they depend on many flow ...

Computational fluid dynamics for cross‐ventilated airflow in an urban building

JAPAN ARCHITECTURAL REVIEW, 2022
AbstractIn this study, the velocity field in a naturally ventilated building within an urban‐like array was explored using large‐eddy simulations. Reduced‐scale building models were used to examine the impacts of the geometric conditions in the surrounding buildings and cross‐ventilating windows on the flow statistics and instantaneous velocity fields ...
