Coupling CFD Simulation and Field Experiments in Summer to Prove Feng Shui Optimizes Courtyard Wind Environments: A Case Study of Prince Kung’s Mansion in Beijing

Feng shui in ancient China was harmonized with the natural environment. The layout of houses following feng is conducive to a comfortable wind To explore positive influence on ventilation, this study takes Prince Kung’s Mansion, which has characteristics layout, as research object. In parallel, assumes dissimilation that lost characteristics. Comparing ventilation courtyards summer for both and through CFD simulation, results were follows: (1) speed values summer, taken from 60 points Mansion by way simulation field experiments, well coupled, proves PHOENICS suitable courtyard environments study. (2) show average zone ratio higher than those during speeds two layouts linearly related. Therefore, more comfort courtyards’ environment layout. (3) front rear pressure differences main can optimize indoor better summer. (4) According evaluation criteria environment, are superior summary, verifies optimizes embodies ecological concept Chinese ancients houses.
