- Abstract:
- Fire dynamies software FDS6 is used to simulate the seenarios of tunnel fire , the temperature distribution of the plume and the maximum temperature of plume impingement zone under the aetion of longitudinalwind are obtained with different fire power. With a new turbulent combustion model, the results of FDS6 showthat the high temperature zone of fire souree foeus on the boltom of plume and a considerable part of plumeheat transfer to ambient by thermal radiation. The heat transferred by eonveetion in plume is redueed, and thetemperature of the plume impact region under tunnel ceiling is obviously lower than the results of FDS5. Themaximum temperature of plume impingement zone under the aetion of longitudinal wind obtained by FDS6 issignificantly lower than the Kurioka model predietions and the tunnel fire experimental values.
