以CFD在城市气候规划中的实际应用为目的，建立了与CFD耦合的建筑冠层模型，探讨了建筑绿化对减少城市热岛效应和降温能量的影响。本文介绍了建筑顶棚内的辐射换热、建筑墙体的阻力模型以及空调系统散热的影响。数值结果表明，建筑物种植可使气温降低0.4-1.3摄氏度，降温能耗降低3-25%。(C)1999爱思唯尔科学有限公司。保留所有权利。
For the purpose of practical application of CFD for urban climate planning, a building canopy model coupled with CFD was developed, and the effects of building planting were discussed for the decrease of urban heat island phenomena and energy for cooling. In this paper, radiate heat exchange in the building canopy, the drag force model of building walls, the effects of heat released from air conditioning systems are presented. Numerical results show that building planting has possibilities for the reduction of air temperature by 0.4-1.3 degrees C and energy for cooling by 3-25%. (C) 1999 Elsevier Science Ltd.
