A Numerical Analysis of Wind Flow within and above Idealised Modified Terraced House Canyon in Malaysia

This study examines the effects of surface roughness (modifications to existing structures) on wind flow. Idealised modified terraced house arrays were used in the study to represent the typical Malaysian terraced house urban-residential neighbourhood. The wind flow characteristics within and above an idealised modified terraced house canyon were investigated, with the idealised arrangement in a square and staggered layout, and the modifications installed 0.5h from the ground. The results indicate that the modifications affected the wind flow because of the smaller canyon width and the sheltering effect of the new obstacle.
