Surface-flow visualization by using infrared thermography and its application to the evaluation of pedestrian-level wind environment around buildings

Abstract

A convenient technique for evaluating the wind environment around buildings in wind tunnel tests has been developed. Infrared thermography and a knowledge-based system are applied to this technique. The evaluation system developed in this study can be used effectively at an early design stage of a tall building development, e.g., when the cross sections and/or the arrangement of buildings are examined from the view point of the pedestrian-level wind environment.
