This paper is concerned with there dimensional flow visualization to examine the adequacy of numerical solution of room air distribution. The shape of room model which is same as the mumerical study in the former report is a cube with outlet at the center of the ceiling and inlet at the bottom center of the side wall. Water is used instead of air for the conveniecnce of visualization, and powder of light cake made of wheat-gluten is used as tracer. Reynolds numbers based on the length and the velocity of outlet are 1000-8000. Some characteristic features of visualized flow are given below. 1) Injected jet falls straight down, 2) then spreads radially over the bottom surface. 3) Upward stream from four corners of the bottom to the ceiling is notable. 4) At the other part upward stream does not reach to the ceiling but recirculates inside. 5) Near the ceiling stream spreads radially from the corner of the ceiling, then falls down at the center. 6) Flow near the inlet is complicated and periodic movement is observed. 7) Flow across the symmetrical plane is seen momentary, but as an average symmetry is maintained.
