The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

his paper studies the impact of changing layering configurations, cavity widths and shading apertures of a shading system on the inner cavity surface temperatures of a double skin façade (DSF) in a hot arid climate. Computational fluid dynamics (CFD) thermo-fluiddynamics modelling is used by coupling RNG k-epsilon turbulence model with Discrete Ordinate (DO) radiation and solar ray-tracing model. The optimized DSF is tested on a peak summer and winter day, at 9:00am, 12:00pm and 15:00pm. A flat-shading with 3 aperture sizes (30%, 50% & 70%) is tested to reduce internal surface heat gains.
