초록
We have performed CFD simulation and analyzed flow and concentration fields for the basic dataof the ventilation system for removing pollutants which were produced in a lecture room. The flowpatterns indicated differently according to the arrangement of openings and the concentration distributionof pollutants were showed higher and lower because of the effect of that flow patterns. In the case ofarranging the openings to the upper and lower side, the stagnation appearance of flow formed in theinterested space. In the case of arranging the openings to the right and left side, the stagnation of highconcentration pollutants appeared in the middle area of the interested space. On the increasing exhaustvelocity, the distribution of pollutants appeared similar to the normal case, but the concentration ofpollutants were lower.
