Research On The Wind Environment Of Multi-patio Traditional Dwellings In Fuzhou

Chinese traditional dwellings are an important part of our country's architectural system.It is the product formed under the influence of the philosophical thought of ancient Chinese "unity of heaven and man".Due to the vast territory of China,in different climate and geographical division formed the east,west,south and north different styles of dwelling types,such as Shanxi cave,Fujian Earth Building,Guangdong Qilou,Beijing Quadrangle.The architectural form,building materials and construction technology of them are not the same.In recent years,with the combination of architectural design and ecology,energy technology,many scholars have begun to use modern science and technology to interpret the traditional dwellings,and re-understanding and inherited the ecological wisdom of traditional dwellings.The reasonable design of natural ventilation is one of the characteristics of climate adaptability in traditional dwelling,it is also the core to study in this paper.This paper discusses the method and principle of the patio on regulating the microclimate of traditional dwellings from the perspective of geomantic theory and modern ventilation theory.This paper takes the traditional dwellings in Fuzhou as the research object,and conducts a census of them.It chooses the well-preserved traditional dwellings as research case from the census results.The basic dimensions of the patio are recorded,and the ratio of the patio is taken as the characteristic quantity.The ideal spatial morphology of patio is obtained by the regression statistics of a large number of data.Then take it as the conditions to choose the case for CFD simulation.Select multiple testing points at the simulation case,compares the simulation results in the testing points with the field measured results,based on the error rate of measured results and simulation results to analysis the accuracy of CFD simulation,in turn,adjust the parameter settings of simulation,to ensure the reliability of simulation results.After the parameters of the simulation are set,the patio's ratio of the simulated case is taken as the experimental variable,and several well models with different geometrical shapes are established for the wind environment simulation.Based on the analysis and comparison of the simulation results,the quantitative relationship between the geometric characteristics of the patio and the wind environment is summarized and summarized from the quantified data.Finally,the experience obtained from residential ventilation design is combined with contemporary ecological architecture design to explore the relevant modern updating and application of traditional methods.The results of this study show that there is no linear relationship between the ventilation effect of the dwelling and the size of the patio.Among them,the best ventilation effect of the experimental group was the model whose patio width and depth ratio are closest to the one of regression statistics.It confirms that in the long process of construction,the residential building has "adaptability" to the natural environment.
