In this study, a scaled model chamber was built to investigate ventilation characteristics of the pump room in tanker and to look into stationary areas of flow field. Experimental study was performed for three kinds of Reynolds number based on the inward velocity and height of inlet port in model by visualization equipment with laser apparatus. The flow pattern reveals the large scale counterclockwise forced-vortex rotation from upside louver to lower scupper toward diagonal corner and also found small eddies at bottom layer.
