Experimental and numerical analysis of a naturally ventilated double-skin façade

An investigation of the octagon-shaped concrete-filled double skin steel tubular columns which used PVC-U pipe to replace the steel tube as inner tube was carried out. In order to study the performances and mechanisms of the components when suffered axial load, ultimate axial bearing capacities of 9 components were tested. The cross-sectional size of the outer steel tube and inner PVC-U pipe and length of the specimen was concerned by the nominal steel ratio and the hollow ratio and slenderness ratio, respectively. The external steel tube and core concrete appeared three and four types of destruction phenomenons, respectively, but the inner PVC-U pipe did not destroy. Finally, experimental results and numerical analysis results were comparied.

Double Skin Facades

The objective of the study was to perform a numerical analysis in order to determine the best position for placing sunscreen inside the channel of a double skin façade insulation relative to dynamic insulation efficiency, using ANSYS-Fluent software. The analysis was performed for summer conditions in forced convection for two airspeed regimes inside the channel: 0.2m/s and respectively 0.5m/s. Regime is considered permanent and the only parameter changed is the position of the blinds in the channel. Results are shown by spectra and profiles of temperature and velocity in order to analyse thermodynamic behaviour of a double skin façade. The numerical results emphasize that effectiveness of sunscreen such as blinds, is proportional to the flow velocity inside the channel and inversely proportional to the distance from the outer glazing. Ranked as the most effective sun protection is when it is located at the outer glazing and air velocity at the entrance is 0.5m/s.
