Study And Analysis On The Outdoor Wind Environment Of Leisure Farm In Hexi Corridor

As the growth of the economic level,people's economic condition is getting better and better,life is getting better and better,the demand for leisure life in their spare time is becoming more and more big,the related construction of leisure farm has developed rapidly with the development of The Times.In fact,leisure place since ancient times is our ancestors to play better,from tao yuanming's arcadia,to xu xiake travel notes,and then to the Summer Palace,the Forbidden City is where love letters.The scenery is perfect,that is to have a pleasant environment,more comfortable play space.In the modern society with advanced economy,we should pay more attention to the comfort and interest of the entertainment environment.However,in the process of construction and use of leisure place,often because the farm groups within the planning and design is not reasonable and cause the farm environment is not comfortable,especially farm to endogenous wind environment caused by the inappropriate.The problem of the wind environment of the leisure farm construction group has an impact on the comfort of the leisure activities of the people in the farm,which will increase the energy consumption of the farm buildings,and also affect the dissipation of the pollutants.With the emphasis on farm environment,more and more researchers hope to solve the quality problem of farm environment.In the planning stages of farm group wind environment is concerned,through the software simulation experiment to research and analysis of the wind environment,find the problems existing in planning and design and to effectively improve.This article through to wuwei liangzhou district and zhangye minle county,in the farm buildings by using the method of numerical simulation to study and analysis of wind environment inside the farm,to understand the original planning scheme under farm group distribution of the aura,and to improve the problems,and to improve farm again after software simulation and analysis,to verify the feasibility of the improved farm scheme construction group.The purpose of this paper is to provide references and Suggestions for improving the plan of the farm building group,improving the comfort of the environment in the farm and solving the problem of outdoor pollutants gathering.The key research contents are as follows:First of all,based on the analysis of environment after the research status of wind farm group,analysis the necessity of farm planning stage wind environment research,and through the comparison of a variety of research methods,using the method of CFD numerical simulation study of wind environment in the farm buildings.Secondly,the main content of CFD software simulation is described.The control equations,discretization methods and calculation rules for the wind environment analysis of farm buildings are selected.The foundation of the study on the wind environment of farm buildings was established by using CFD software.Third,this paper select wuwei liangzhou district and zhangye minle county as the research object in the new leisure farm buildings,introduces the case study of leisure farm basic situation and the basic conditions of the area.Using PHOENICS software to simulate the farm group,introduce the software characteristics and the advantages of simulated wind environment.Fourthly,by using the Sketch UP software to make the farm plan specific,the PHOENICS simulation was used to simulate and analyze the wind environment of each season in the leisure farm.Through the analysis of the wind environment results of the farm buildings group,the general distribution rules of the wind environment in the farm buildings were summarized,and the areas with poor wind environment in the farm were analyzed.On his farm based on the analysis of wind environment research,put forward specific improvement scheme of farm groups,and by using simulation software simulation analysis was carried out on the improved farm plan again,to verify the improvement scheme is feasible on a farm.In the end,the author puts forward Suggestions on improving the wind environment in the construction group of the leisure farm buildings,and realizes the combination of wind environment analysis and improvement theory and the practice of farm planning and construction.In this paper,the research for the wind environment evaluation in the farm buildings to lay a solid foundation,to provide effective guidance to the planning of leisure farm,the improvement advice for farm wind environment,can let the designer to effectively solve the farm wind of leisure farm environment brings a series of questions.
