Experimental studies of combined heat transfer in turbulent mixed convection fluid flows in double-skin-facades

摘要

The current contribution describes the experiments performed in an outdoor test stand for so called "double-skin- facades" at the Technical University of Munich. The purpose of the investigation was to determined the time and local- averaged overall heat transfer coefficients for solar radiation augmented turbulent mixed convection flows in trans- parent vertical channels. The external plate of the vertical channel is formed with horizontally oriented ventilation gratings in the external glass facade, thus providing openings for the air circulation within the gap.
