| Outline of Final Research Achievements |
In this study, there are two main themes : (1) investigation on turbulent transport mechanism of scalar and momentum, (2) development of evaluation method for wind environment in an urban area. The followings are shown. (a) Turbulent structure which causes large momentum transport are visualized based on conditional averaging method. (b) New prediction equation is proposed to express wind environment at a pedestrian level by using geometrical parameters. (c) Probability densities of wind speed at a pedestrian level shows similar function of normalized probability variables defined by the mean and the standard deviation of wind speed. (d) The strong correlation are observed between wind speed near roughness elements and those pressure.
