Indoor And Outdoor

Through FLUENT numerical simulation, this paper is aimed on studying the influence of outdoor wind environment on indoor environment. We found that building height, building layout format and opening format in the wall are significant impacted on indoor natural ventilation. At the three-fourth height of building, if the building layout and housing opening is stagger, it can get high-quality indoor natural ventilation and more evenly indoor wind field.

Rng Turbulence Model

This paper adopted computational fluid dynamics (CFD) method, used k-ε RNG turbulence model-closed control differential equations for numerical simulation. Through numerical simulation and analysis of wind environment in a middle school campus, the round wind field under dominant wind direction was got in the summer and winter. According to the results of velocity field and pressure field, analysis the wind environment, compared the influence of wind direction and surrounding buildings space to the natural ventilation, provided guidance introduce for the layout of the school.
