A Study on the Smoke-logging Phenomenon caused by Water Mist

Water Mist 분무액적에 의한 스모크-로깅현상에 관한 연구

This study contemplated the descending air current from the smoke layers related to the smoke logging phenomenon in the Water Mist applied design for effective evacuation safety design. As a result, database on the average particle diameter, particle velocity and distribution of sprinkling was obtained and the relationship between the water amount and particle diameter was obtained. Also Descending smoke velocity was significantly faster to 9.8m/s, it is determined that appeared rapidly by a high water pressure.
