传统岭南民居自然通风数值模拟研究

摘要

G ood ventilation perform ance is especially im portant for dw elling in L ingnan region, adapting the hum id subtropical clim ate and high urban density. N atural ventilation m ode in the traditional dw elling called bam boo-tube house w as num erically investigated by C om putational Fluid D ynam ics (C FD ), and a change behavior of ventilation perform ance w ith patio dim ensions w as focused studied.%岭南地区气候湿热，城镇建筑密度高，因此民居空间通风性能尤为重要。本文以岭南地区传统民居形式竹筒屋为研究对象，对其自然通风模式进行C FD 数值模拟分析，重点研究室内通风性能随天井尺寸的变化规律。关键词：传统民居自然通风热压拔风 C FD
