Research On The Optimization Of Wind Environment Of Commercial Pedestrian Street In Cold Area Based On CFD Simulating

With the progress of the continuous economic and society development, commercial pedestrian streets were built throughout the country, people start to pay attention to the quality of the wind environment of the commercial pedestrian streets. The combination of various forms of space will change the airflow within the buildings, and the wind environment level will directly affect the citizens in the comfort of outdoor activities. For cold city, therefore, citizens to provide a safe, comfortable, energy-saving cold commercial pedestrian block, is a hot topic in today’s research.Based on the Chinese baroque buildings in the typical cold area city. Harbin as an example, from the cold climate conditions and the characteristics of the architectural layout, by CFD software for the Chinese baroque buildings within the typical street space, courtyard space and the square space for wind environment simulation. According to the wind environment evaluation system to study the architectural layout, orientation and wind environment and found that the relationship between present situation toward the next space wind environment problems. Finally, on the basis of summarizing the predecessors’ research and above research, through the CFD simulation of wind field characteristics of buildings, building wind environment characteristics of surround close space and wind barrier of wind environment to improve the ability to expand and style study the relationship between the building layout and wind environment research, so as to conclude the way to solve the problem of wind environment. Combined with previously discovered Chinese baroque buildings of above found wind environment, wind environment optimization design problems, and through the design example building layout summarizes the architectural layout style environment optimization model has universal applicability, monomer building wind optimization model and wind barrier design patterns, applied in the cold to commercial pedestrian block outdoor wind environment optimization.This paper in the process of research, the integrated use of the CFD simulation, comparison and analysis, summarized method by CFD to simulate the wind environmental problems in the planning of realization, analysis and optimization in the visual problems, summed up the architectural layout and the rule of wind environment and planning stroke environment design, the method of the planning and design parameter, and provide scientific theoretical basis for wind environment and design of commercial pedestrian block.
