Analysis Of Harbin Riverside Settlements Design Strategy Based On Wind Enviroment Simulation

With the rapid development of urbanization and the city in recent years,the users gradually change single functional requirements to the comfort needs.Among them,the outdoor microclimate environment and its mitigation effect on the heat island has been paid more and more attention.The intercity environment in the city has an important role in improving the outdoor wind environment.At the same time,because of riverside residential area can increase the geographical advantage.So the riverside area outdoor wind environment has a more effective guiding role.In this paper,the research object is selected as the riverside residential area in Harbin.Based on the FLUENT simulation software in CFD,the winter and summer simulation of the research object is carried out.The design strategy of Harbin riverside residential area based on outdoor wind environment is obtained by analyzing and refining the simulation results.The main contents of this paper are as follows:By analyzing the climatic characteristics of Harbin,and the boundary conditions are determined for the simulation experiment.Combined with other weather data in Harbin,the winter and summer led the wind direction and wind speed,set the boundary conditions.Through the field measurement and other informations,the target area of the layout statistics can get the area model,in order to establish the post zone model for the wind environment simulation to prepare.By simulated by FLUENT,results are analyzed by wind speed ratio evaluation method and the wind speed calculation point arrangement.Based on the simulation results of different seasons,the outdoor wind environment strategy of winter and summer in Harbin riverside residential area was extracted.Building as an important carrier of human settlements,its comfort,the importance of security can not be ignored.At the same time,due to the existing research stage,there are few studies on the outdoor wind environment in the riverside area of the cold area,and the object of this paper is specific,which can also provide reference for the design of the waterfront in the cold area,and can also provide the basis in improving the wind environment.
