Quarter-Scale Modeling of Room Fire Tests of Interior Finish

摘要

A technique for modeling fire build-up in rooms with combustible interior finish was refined to achieve closer simulation of full-scale fire development. Fire experiments were performed in one-quarter scale model rooms and full-scale rooms having a doorway opening. The interior finish test materials were nitrile foam rubber, fibrous glass, and plywood; a gas burner was employed as the fire source in a rear corner of the room. It was necessary to lower the doorway in the model by as much as 14 percent to obtain flashover with the same equivalent heating rate that produced flashover in the full-scale test. At the same time, the width of the doorway in the model was increased appropriately to maintain the same volumetric air flow rate.
