摘　　要：智能医疗建筑不同的空间布局对自然通风气流有着不同的影响,为此需要通过建模分析其中的影响关系。该文采用离散化处理方式确定智能医疗建筑单位空间内流体增量,数值化处理自然通风流场形态和气流组织特性;根据空间句法理论将智能医疗建筑空间布局抽象为拓扑关系图,计算智能医疗建筑空间布局与自然通风气流数值指标间的变化系数;以此搭建智能医疗建筑空间布局对自然通风气流的影响模型,并与现行的“动态估算模型”、“三维非稳态湍流场模型”进行计算能力的量化比较。该文所构建模型的单行纵向加速性能、并行横向拓展性能、模型运算能力均具有较优的水平,其中运算能力系数均值为4.25,高于“动态估算模型”的3.5和“三维非稳态湍流场模型”的3.85。基于空间句法理论、采用离散化处理方式构建的影响模型表现出较优的计算能力。Different spatial layouts of intelligent medical buildings have different effects on natural ventilation airflow,so it is necessary to analyze the influence relationship through modeling.In this paper,the discrete processing method is used to determine the fluid increment in the unit space of the intelligent medical building,and the natural ventilation flow field shape and air distribution characteristics are numerically processed.The coefficient of variation between the spatial layout of the building and the numerical indicators of natural ventilation airflow.The influence model of the spatial layout of the intelligent medical building on the natural ventilation airflow is built,and the current dynamic estimation model and three-dimensional unsteady turbulent flow field model are used to carry out quantitative comparison of computing power.The experimental results show that the single-line vertical acceleration performance,parallel horizontal expansion performance,and model computing capability of the model constructed in this paper are all excellent.The average computing capability coefficient of the constructed model is 4.25 higher than 3.5 of dynamic estimation model and 3.85 of three-dimensional unsteady turbulent flow field model.The influence model constructed by using the discretization processing method based on space syntax theory shows better computing ability.
