| Research Abstract |
"A Coupled Simulation of Heat Balance Simulation and Numerical Simulation" is expected to be the computer aided design tool in outdoor space. Compared with existing prediction methods, this method places greater emphasis on its ability to make it possible to evaluate thermal radiant environment, air temperature, and wind distribution that are given to the timely prediction in design process. By the use of this coupled simulation method, the micro-climate of Metro Manira's two dwelling areas were studied. It was confirmed that the thermal improvement model was effective for the improvement of thermal radiant environment and airflow environment in outdoor space compared with the standard model of existing urban area, it was also confirmed that the proposed simulation method was effective as the computer aided design tool in outdoor space.
The Prediction method of heat balance simulation that is one of main programs of coupled simulation was combined with 3D-CAD system that makes it easily to input the complicated external shape and also make it possible to evaluate the 3-D distribution of surface temperature at any view points. The heat balance simulation was used on trial for thermal problem study of an existing small residence area in Tokyo that is composed of five houses and big crown trees, it was confirmed that the heat balance simulation was so effective as to evaluate the thermal influences that were given by the differences of outdoor space design.
