A visualization of internal and external flow in single dwelling model with cross ventilation is conducted in wind tunnel. A fine alumina powder is used as tracing agent and a light sheet obtained by spreading a laser beam is used as a light source.The flow patterns in vertical sections and horizontal sections are photographed with various parameters of opening's position and room numbers in the model. Useful data are obtained for designing the natural ventilation systems through openings in this study.
