摘　　要：以中间侧送风、下回风的流场作为数值计算及实验研究的模型 ,在对数学模型及物理模型进行理论分析的基础上 ,对常规下的K ε模型进行了修正 ,并运用K ε紊流模型计算了空调房间的气流组织 ,用离散方法对边界条件进行了处理 ,并把数值计算结果与实验结果进行了比较 .实验结果证明运用K ε紊流模型计算空调房间的气流组织是可行的 。The type of flow and temperature field is analyzed in the article. Simulation and experiment are based on a field where cool air discharges from vertical jet and returns to machine at the pass below the vertical jet. The mathematical turbulence model used is a revised K ε turbulence model that takes the effects of anisotropic characteristics of nonisothermal flow fields into account. The accuracy and reliability of numerical simulation for two dimensional nonisothermal jet based on the revised K ε turbulence model are clarified by comparing the results of numerical simulation with the experiment
