dc.description.abstract	The effects of different states of air supply and airflow patterns on temperature gradient distribution are calculated and analyzed with the help of FFSV3.0 software, using the LB models and LES and RANS methods. An experimental study with upper supply and upper return air flow was performed in normal airflow room. The results were compared with numerical simulation results and were found to agree well. Information on delaminating laws, and measurements of the relationship of delaminating heights and air supply temperature and velocity is also presented. According to the simulation results, a formula that avoids hot air delaminating in ceiling air supply is derived, which can guide engineering design.	en
