as a research engineer.
Jack was chair of the National Fire Protection Association technical
committee for the Standard on Water Mist Systems (NFPA 750) from 1993 to
Beginning with testing of a water mist system for Heavy Goods Vehicle (HGV)
transport rail cars for the Channel Tunnel in 1997,
full-scale fire testing of water-based suppression systems conducted at
tunnel test facilities in Switzerland, Spain, Norway and England.
usefulness of test data. By
using specific fire test data to calibrate a CFD model of the test
structure, they made it possible to examine
tunnel configurations and ventilation conditions that differ from the test
arrangement (within limits), thus increasing the value of the test data.
Current design approaches for passive structural fire protection, and for
ventilation systems in tunnels are based on assumptions of unsuppressed
fires. Jack is particularly interested in incorporating the benefits of
suppression systems into standard design procedures for structural fire
protection and ventilation systems in highway and rail tunnels.
We are pleased to welcome Jack back to
