In general, visualization experiment in a conventional boundary layer wind tunnel for buildings is a difficult task to carry out. This research intends to conduct the visualization experiment through the direct observation on the
surrounding wind flow. The occurrence of flow separation along the surface is preliminarily observed. By high-speed camera, the location of the separation point moves forward to the downstream as the Reynolds number increases.
