건축설비용 수충격저감 공기실의 과도 압력 특성에 관한 수치연구

A numerical study has been conducted to characterize the transient pressure in a water supply system for building service applications. The system includes an air chamber to reduce the water hammer occurred in it. A commercial code, Flowmaster2 Version 5.2, emplying the method of characteristics has been utilized to simulate the unsteady behavior of the system, especially to investigate the effect of the volume of the air chamber. Preliminary results of the study agree quite well with the previously reported. More detailed results will be reported later.
