Evaluation of Monte Carlo method for modeling glazing behavior during radiant exposure

Abstract

Radiant heat transfer is an important issue when analyzing the thermal behavior of glazing during a fire. In this article, the Monte Carlo method (MCM) is evaluated for modeling the behavior of glazing that is exposed to thermal radiation. MCM can account both for radiant heat transfer across the thickness of the glazing as well as the spectral nature of the glazing. A calculation tool is developed to model the glazing temperature and the time when the first cracking occurs using MCM. Comparisons between the predictions and past experiments are made for glazing with different geometries exposed to various radiation levels. Reasonable agreement is obtained. Factors influencing glazing behavior are also studied using the MCM calculation tool. Language: en
