CFD Simulations to Predict Comfort Level of Outdoor Wind Environment for Taipei Flora Exposition

Article Preview

Abstract:

The goal of this investigation is to conduct the CFD analysis in conjunction with the wind comfort level standard to predict the pedestrian wind comfort level around the Dreams, Angel Life and Future pavilions in the Xinsheng Park of the Taipei International Flora Exposition. The computerized airflow simulations were carried out to predict the detailed flowfield for determining the comfort level of outdoor wind environment for three pavilions in the Xinsheng Park. In order to generate the suitable environments of natural ventilation for visitors, the calculated results can be used to appraise the sufficiency of natural ventilation for the open space around the building cluster.
