Abstract: The exhibition hall of Wuhan International Expo Center has a huge building volume. The fire separation water curtain of 80 m (width)×11 m (height) is used between the exhibition halls, which greatly exceeds the size limited by the current fire code. The effectiveness and reliability of the water curtain system in the exhibition hall can only be verified through field tests, so as to confirm whether the water curtain system can really play the role of fire separation. Through the field fire test, it can be concluded that the water curtain forms a complete and thick "water wall" between the exhibition halls, which effectively prevents the smoke from spreading to the adjacent exhibition halls.

Key words: fire separation water curtain, test, fire protection, smoke isolation, flow
