抄録

A field measurement on thermal balance and flow characteristics of a full-scale 2D canopy was done, and following phenomena were observed. 1) Air temperature distribution and sensible heat flux of canopy surfaces show the high irregularity due to the sunshade. 2) Linear relationships exist between wind speed Uim and convective heat transfer coefficient (CHTC) of most measurement points. The linear regressions of SAT meters fixed on a leeward wall show similar tendency, in contrast those on a windward wall vary with the position. This tendency is consistent with those of former wind tunnnel experiments. 3) CHTCs of walls deduced from measurement result of surface thermal balance show different tendency of those of SAT meters. It may be caused by the effect of the unhomogeneous temperature distribution of canopy.
