Abstract

In this study, the performace of using radiant barrier in inclined roof was numerical investgated by using the COMSOL Multiphysics software package. A roof was simulated as two parallel plates with an air gap in between for enhancing ventilation through convection heat transfer. The simulated results were validated using a published experimental work. Results suggests that a maximum of 89% reduction in the heat gain through the roof for a heated channel with a uniform heat flux of 650 W/m2was possible. Moreover, the roof inclination angle reduces the heat-gain through the roof up to 41.5% for an inclined angle of 75 degrees.
