摘要 自然通风的控制方程为非线性的二次方程组,因此具有非线性动力特性的表现,如气流的多解和流动的多样性现象。本文以两区域的冷热源自然通风为研究对象,通过建立物理模型的流动与能量方程得出其控制方程组,从而用数学的方法求解得出流动所可能出现的模式,结果很好地展示了自然通风多解性现象。 The govern equations for natural ventilation is a sets of non-linear equations, so the flow has the characteristic of non-linear dynamics. For example, the results have multiple solutions and the flow has diversity phenomenon. In this paper, natural ventilation of two-zone building with heated and cooled source is investigated, and the govern equations for the physical model is set by flow and energy balance equations and solved by mathematics methods to reveal the flow patterns and the multi-solution phenomenon of natural ventilation.
