In our former studies on the thermal boundary layer in the corner of wall, we proposed the thermal boundary layer equivalent to convective heat transfer (TBLC) for the practical thermal boundary layer in calculation of overall heat transmission, and classified the thermal boundary layer in the corner of wall in 10 types, and experiments by using Thermo Viewer have been undertaken under the limited condition, and, on the same conditions, numerical analysis was carried out. And empirical formula of the thermal boundary layer equivalent to convective heat transfer in each corner was obtained. In the present study, experiments by using Thermo Viewer and numerical analysis by Finite Element Method are made by applying the empirical formula of the thermal boundary layer equivalent to convective heat transfer in each corner to both internal-angled corner and external-angled corner in overall heat transmission analysis of wall corner. From the results mentioned above, we may conclude that empirical formula of the thermal boundary layer which we proposed can be appricable with united together to the numerical analysis of wall heat transmission by Finite Element Method.
