A STUDY ON DESIGN METHODOLOGY FOR OUTDOOR THERMAL ENVIRONMENT BASED ON CFD ANALYSES : Analyses of the effect of wind from rivers on outdoor thermal environment

Abstract

In this paper, the effects of wind flow from rivers on outdoor thermal environment in the site for apartment houses, which locates near rivers, were investigated. First, a CFD analysis was carried out for day-time in summer. Then, a CFD analysis for the situation where one river was covered by asphalt was also carried out. Furthermore, suitable building layout for leading the wind from rivers to the targeted site was discussed based on CFD results. With the modified layout, the results showed significant improvement of outdoor thermal environment. It is shown that CFD can be a very useful tool for outdoor environment design.
