Abstract
Wind catchers are considered as one of the oldest natural ventilation systems. During the past decades, several studies have been conducted to revive and re-use the wind catcher systems for thermal comfort. However, limited studies have considered the wind engineering perspective where the surrounding flows can influence the ventilation process. Therefore, the objective of this study is to analyse the flow behaviour inside a two-sided traditional wind catcher building for a better understanding of the influence of the external airflow on internal ventilation behaviour. The study was conducted experimentally in a wind tunnel and through CFD simulations using the standard k-ε turbulence model. The effect of two different surface terrains and two different locations of the wind catcher building, beneath the tunnel floor with only the wind catcher tower above the floor (as in several previous studies) and above the tunnel floor were investigated. It is concluded that more representative experimental methodologies should be used when studying natural ventilation with wind catchers.
