An experimental investigation has been conducted in order to give insight into wind flow characteristics in urban areas, in particular, its effects on low-rise buildings. Analyses are based on the results from atmospheric boundary layer wind tunnel experiments. Building model is a 1/75th scale model of a low-rise tilted house with roof inclination of 45°. Aiming to introduce the effects of neighbouring buildings, a comparative study of two configurations is presented, one with isolated principle building and another with four similar buildings surrounding the principle one. Additionally, the influence of the wind approaching angle is considered through the analyses of three directions: 0°, 45° and 90°. Wind velocity profiles above the roof of the principal building and pressure distribution on its surface are analysed in the paper. |
