Numerical analysis of air flow in double skin facade (DSF) with thermal mass

Abstract

Paper presented at the 7th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Turkey, 19-21 July, 2010.

This study was performed to analyze the impact of two parameters on the airflow: the velocity of air at the inlet and the type of the blind. The type of the blind has a major impact on the temperature distribution and on the velocity profiles in the cavity. On the other hand, thermal mass increase the energy performance of natural ventilation. The main objective is to generate the performance data of concrete thermal mass and their contribution to energy efficiency of the system by predicting thermal profiles in the double-skin fa e, and the resulting cooling/heating loads for the adjacent perimeter interior zones during extreme summer/winter conditions.
