| Abstract: | Based on full-scale experimental simulation,the smoke characteristics under applications of water mist and mechanical ventilation were studied.The wind flux and speed were adjusted through changing of the transducer frequency,while the position and size of smoke vent were changed through blocking,then the temperature and CO concentration under applications of water mist and mechanical ventilation were tested and analyzed.The results show that,with increase of smoke ventilation intensity,the fire extinction ... |
