THE MOVEMENT OF BUOYANT FLUID AGAINST A STREAM AND THE VENTING OF UNDERGROUND FIRES

Thomas, P.H., 1958. THE MOVEMENT OF BUOYANT FLUID AGAINST A STREAM AND THE VENTING OF UNDERGROUND FIRES. Fire Research Notes 351


ABSTRACT

The movement of smoke and hot gases in underground tunnel fires is discussed and some numerical data given for the backflow against the flow. The use of a forced ventilation installation to clear the smoke is considered and it is suggested that in general little is to be gained from it. The creation of a natural draught may be a more useful method of clearing heat and smoke.
