摘要 采用非线形动力学方法分析了热源强度给定情况下的风力与热浮力共同作用的简单四开口建筑的自然通风的动态特性,包括多解的存在性及其稳定性、多解存在区域的特征参数范围,最后用MIX模型验证解的稳定性对室内初始温度的依赖性。 A non-linear dynamic method is used to analyze dynamic behavior of natural ventilation driven by both wind and thermal force in four-opening building when indoor heat source strength was given, including the existence of multiple solutions, the stability of solutions and the feature parameter range in which multiple solutions exist. At last, MIX2.0 is used to validate the stable solutions depend on initial indoor temperature.
