Research on Indoor Thermal Environment of Building Corridor Based on Numerical Simulation

Abstract

Abstract As an important connecting structure between modern buildings, because of its closed structure and high frequency of people’s passing, the local “greenhouse effect” formed by solar radiation causes strong discomfort to human body during the summer in northern China. In this paper, a building corridor in Tianjin is modelled by CFD, and the internal environment of the building corridor is simulated by turbulence model, heat transfer model and radiation model. It is found that K - ε model and DO radiation model in the numerical method can be used to simulate the internal thermal environment and solar radiation conditions of the building corridor. According to the distribution of air temperature and velocity in the corridor, a new type of building should be proposed in further study.
