Numerical Simulation Research On Traditional Residence Wind Environment In Southern Hebei

With the development of economy,technology,and the improvement of living standards,creating a pleasant,comfortable and healthy human living environment has become the aim which people are pursuing.Quality of wind environment is an important index to measure the human living environment,excellent wind environment is precondition and guarantee of comfortable,healthy,safe human living environment.In the context of our country's efforts to promote the revitalization of the countryside,development of traditional residence had been accelerated,the construction of human living environment is becoming more and more important.This paper combined with the climate characteristics of southern Hebei,research for the traditional residence wind environment,explore the design parameters of traditional residence to create a good wind environment,so as to provide reference for the design of traditional residence in southern Hebei.In this paper,firstly,penman did a survey of traditional villages in southern Hebei,got the data of local traditional houses,influence factors of traditional residence wind environment are analyzed,building storey height,depth of colonnade eaves,distance between principal room and wing-room,length-width ratio of the courtyard,azimuth of building is determined as the factor.Secondly,setting the parameter threshold and simulation cases of each factor based on the investigation about traditional residence of southern Hebei,the Phoenics computational fluid software is used to simulate the cases of each factor one by one,and the ideal parameters of each factor are judged according to the evaluation index of wind environment in this paper.Then,analyze the two factors coupling of each factor ideal parameters,the effect of two factors ideal parameters coupling on the traditional residence wind environment in southern Hebei is explored.Finally,all the ideal parameters of the factors are coupled,the Phoenics computational fluid software is used to simulate the whole factor coupling case once again,evaluate and compare the numerical simulation results of each cases,and then put forward the optimization strategy and optimum design parameters of traditional dwellings.
