JET FLAME ATTACK ON VESSELS

This paper presents an overview of activities related to jet fires int eracting with obstacles as carried out within the CEC-sponsored projec t JIVE. A modelling technique and experimental data related to the det ermination of heat transfer from jet fires to obstacles such as pipewo rk and vessels are presented. Conclusions can be drawn from these stud ies regarding the maximum heat flux to be expected in methane jet fire s. The heat flux distribution on obstacles can be very non-uniform, de pending on the distance between the origin of the flame and the obstac le. This non-uniformity leads to thermal stresses in the obstacle and will obviously affect the resistance of the obstacle to the fire.
