説明

This research attempted to analyse the thermally distributed flow by using the Schlieren image. By arranging two dimensional building models with heating floor, thermally distributed building canopy space was established in the wind tunnel. In the Schlieren images, dense color zones, which show the existence of steep temperature distribution according to the principle of Schlieren were observed at the top of building canopy and near the ground surfaces. The same tendency was verified in the temperature measurement data of the wind tunnel. This research also indicated that temperature distribution inside the wind tunnel could be quantified with high precision by the Schlieren image analysis, applying the quadratic function of brightness.
