Research Abstract

This study developed a visualization method for convective heat transfer coefficient (CHTC) distribution in urban spaces using a 3-D laser scanner and filter paper evaporation method. The relationship between the water content of filter paper and laser reflection intensity was quantified, and the method to estimate CHTC was proposed using water potential and the Lewis equation. The proposed method was applied to a small building with simple geometry, and the applicability and limitation of the method were confirmed. Lastly, the method was applied to a large-scale building with complex geometry, and the characteristics of CHTC distribution were clarified.
