영문 초록

This study described on that how to decide effective ventilation plan in the indoor place where contains air pollution source. Then it mentioned indoor air current and transferring of contaminant. We considered and compared the results of experiment with computational fluid dynamics numerical analysis. The experiment has the same geometric structure and boundary conditions of numerical analysis. We measured flow velocity and concentration distribution in indoor place. Both results of the experiment and numerical analysis showed similar output. If the same diameter of admission and exhaust mechanism, the shape of admission and exhaust mechanism influences on flow distribution of indoor air current and concentration distribution of contaminant but the shape of exhaust mechanism does not affect them. If the contaminant occurred in center of inside room, it has more influenced than other position, So shape of admission mechanism must be considered properly shape of admission mechanism. The shape of admission and exhaust mechanism have excellent ventilation function with aspect ratio of 4 without air pollution occurring position. Also, the left side ceil admission mechanism has excellent ventilation function without air pollution. Being an admission mechanism under the right wall side bottom, being an exhaust mechanism under the right wall side bottom area evaluated the best position among them without air pollution.
