| 요약2 | With the recent increase in interest in indoor PM and the use of CFD, many studies on indoor PM use CFD. However, in CFD analysis of indoor PM, there is a limit to realizing the same number of particles as in the experiment due to problems of analysis time and physical specifications of the equipment. For this reason, although a limited number of particles is generally used, studies on an appropriate number of particles are scarce. Therefore, in this study, the R2 , Cv (RMSE), error rate of the results and analysis time according to intervals of the initial uniformly distributed particle were compared. In the CFD analysis space of 8 m3 volume, the residual particle concentration after 1 hour of ventilation was compared and analyzed. The Case with the IP (Interval of initial particles) of 40 cm also showed a high correlation based on the case with the IP of 2.5 cm. Considering both the analysis time and the reliability of the results, it is judged that the IP of this analysis is 10 to 20 cm appropriate. |
