Abstract

The Schlieren method is an effective way to visualize the thermal flow under the condition of low velocities. This research aims to clarify the relation between the Schlieren images and the temperatures by using thermal stratification wind tunnel. As a result, when rooftop of the single building was heated, the extent of thermal influence could be obtained by the Schlieren images. In the case of 2D-buildings with heated ground, the relationship between the vertical temperature gradient and the brightness devised from the Schlieren images were clarified.
