Abstract

In recent years, double-layer roof systems with porous panels have been widely used due to their excellent thermal insulation function, but the wind pressure distribution of each layer of double-layer roof is quite different from that of traditional bare roofs. To solve the problem of whether volume distortion is required for the double-layer roof test, this paper takes the double-layer roof structure with porous panels as the research object and studies the influence of volume distortion on the mean wind pressure coefficients of the double-layer roof system by Computational Fluid Dynamics, and the Helmholtz resonance in a double-roof system is further illustrated. The results show that there is Helmholtz resonance in the double-layer roof system, and the volume distortion influences the mean wind pressure coefficients on the upper surface of the roof. Volume distortion has an impact on the internal pressure of a double-layer roof system. If there is no volume distortion, the amplitude of the internal pressure of the double-layer roof system will be underestimated. Volume distortion should be taken for the double-layer roof system in Computational Fluid Dynamics.
