Visualization of Wind Environment in Urban and Architectural Spaces

Abstract

To mitigate urban heat islands, the use of the sea breeze, which transports a large amount of urban heat to outer areas, is potentially effective for urban air cooling. In this project, the Earth Simulator, a powerful super computer system, was applied for the first time to find a solution to an urban environmental problem. The CFD technique was adopted to simulate air flow and temperature fields with a 5-m horizontal resolution over scales ranging from the building scale to the entire area of the 23 wards of Tokyo.
