WALL2D: a Model for Predicting Heat Transfer through Wood-Stud Walls Exposed to Fire

摘要

WALL2D, a two-dimensional computer model for predicting heat transfer through uninsulated wood-stud walls protected by gypsum board, has been under development at Forintek for several years~1-5. This paper describes major revisions which improve the description of heat transfer through the entire assembly, but, most notably, across the cavity. WALL2D's predictions for time-dependent temperature profiles in wood-stud walls are in very good agreement with the result of both small-and full -scale fire resistance test. Although further refinement of WALL2D will continue, the model, in its current form, is suitable for application to fire safety engineering design.
