Abstract
The topic of double-skin façades (DSFs) is re-emerging in the research environment, with studies ranging from architectural design concepts to specific investigations of heat and mass transfer in a vertical channel. These studies reflect a lack of comprehension of the phenomena taking place within the DSF cavities. This work presents a case study, where the Laser-Doppler Anemometry principle, combined with video registration of smoke movement, is used to establish the velocity and flow patterns in an asymmetrically heated ventilated channel in a controlled environment. The authors of this work contribute to the research field by addressing the pros and cons of the Laser-Doppler Anemometry approach for the measurement of the vertical velocity component in a DSF and presenting an example of obtained experimental results for the validation of CFD models. The results of this work address the velocity distribution for the vertical 2D cross plane of the DSF cavity. The analysis of the measurement data includes an assessment of the stability of the flow and fluctuations throughout the measurement period.
