Estimation of air temperature in a compartmental fire with forced ventilation using ventilation theory

Abstract

A simple model is proposed to calculate the air temperature in a compartmental fire with forced ventilation.  The model is based on the mixing process in displacement ventilation theory.  This is reasonable as the air intake rate in a forced ventilation chamber can be fixed at a certain value.  Expressions for the hot air temperature are derived by considering the cases with and without a plume region.  Experimental studies in a small chamber with forced ventilation were performed to verify the predicted results.
