摘　　要：应用计算流体力学(CFD)软件FLUENT对扇形教室空调通风进行了三维数值模拟。采用了标准的k-ε模型计算了扇形教室的速度矢量场与温度场,并对结果进行深入分析。根据分析结果,通过对原扇形教室内速度矢量场、温度场不均匀区域进行优化调节,提出了两种方式改变扇形教室的模型,并分析其内部的速度矢量场以及温度场,从而验证其改进模型的有效性及可靠性。The 3-D numerical simulation of the ventilated fan-shaped classroom is applied by computational fluid dynamics（CFD） software FLUENT. The k-ε model is utilized to calculate the velocity vector field and temperature field of the ventilated fan-shaped classroom,and analyze the results.According to the uneven region of velocity vector field and temperature field in the classroom,we present two ways to improve the model of the classroom,and analyze the velocity vector field and temperature field,and verify the effectiveness and reliability of the improved model.
