基于CFD风环境模拟的既有体育馆改造为方舱医院的可行性分析——以哈尔滨某体育馆为例

FEASIBILITY ANALYSIS OF TRANSFORMING EXISTING GYMNASIUM INTO SHELTER HOSPITAL BASED ON CFD WIND ENVIRONMENT SIMULATION:TAKING A GYMNASIUM IN HARBIN AS AN EXAMPLE

突如其来的新冠肺炎疫情使得体育馆成了应对公共突发卫生事件、进行方舱医院适应性改造的后备力量。本文分析了多个已被改造为方舱医院的体育馆室内围合形态,以哈尔滨某体育馆比赛场地区域作为研究对象,在原有体育馆室内形态的基础上进行CFD风场模拟,根据武汉既有体育馆室内风环境改造原理提出两种改造方法,通过风场模拟,得出室内水平及垂直风场的分布结果,并与方舱医院病房区风环境要求做对比,分析得出既有体育馆改造为方舱医院的可行性,为方舱医院改造提供一定的理论支撑。

The sudden COVID-19 made the stadium a reserve force for dealing with public health emergencies and improving adaptability of shelter hospitals.This paper analyzes the indoor enclosure of gymnasium which has been transformed into square cabin hospital.Taking a gymnasium competition area in Harbin as the research object,CFD wind field simulation is carried out on the basis of the original indoor form of gymnasium.According to the principle of indoor air environment transformation of Wuhan existing gymnasium,two methods of renovation are proposed,through wind field simulation,The results show that the indoor horizontal and vertical wind field distribution results,and compared with the ward area wind environment requirements of the fangcabin hospital,the feasibility of the existing gymnasium transformation into the square cabin hospital is analyzed,which provides a theoretical support for the reconstruction of the square cabin hospital.
