CFD-Based Simulation Analysis of Indoor and Outdoor Ventilation Environment

With the acceleration of China's urbanization, living environment has become a major consideration of residents. Natural ventilation, as an important component of living environment, has therefore received more and more attention in the designing and building of residence. The paper introduces CFD technique to simulate flow field, and employs SIMPLE algorithm and QUICK difference scheme to conduct steady state calculation. Then based on zero-equation model, the paper implements a simulation analysis of the flow field distribution inside and outside the residence from the perspective of atmospheric thermodynamics and dynamics. The focus of the paper is a simulation of the variation of wind flow field. Through analyzing the aerostatic zone and minor wind zone inside and outside the residence, this paper provides constructive suggestions for optimizing the design of residence.
