COMPUTATIONAL FLUID DYNAMICS FOR DESIGN

摘要

The understanding of natural phenomena in relation to buildings, and in particular internal and external air flow, is becoming increasingly important to architectural design. This is due to the increased complexity of contemporary buildings1 and a growing interest in improving building performance in terms of environmental impact.2 Computational fluid dynamics (CFD) is a cost-effective technique widely employed in industrial design. While indoor analysis can be achieved via CFD, for outdoor studies wind tunnel testing (WTT) is still the prevailing mode of analysis. Moreover, WTT is often performed only a few times during the course of a building design/construction cycle for verification purposes. The CFD versus WTT debate has been around since the introduction of CFD several decades ago; both methods provide a certain degree of knowledge and understanding of the environment in which the design exists.
