Numerical simulation of indoor thermal environment of a double-skin facade office with different shutter angles

摘要

Airflow and heat transfer simulation was conducted for a double-skin facade (DSF) system equipped with shading devices in the cavity, using computational fluid dynamics (CFD) with RNG turbulence model and PISO algorithm, for five conditions of slat angles (θ=0°, 30°, 45°,60°, 90°). The present study indicates that the presence of shading devices influences the temperatures, the ventilation rate and the air distribution in the DSF system. Besides, the different angles will make different influences.
