研究了基于大涡模拟（LES）、微分应力模型（DSM）、代数应力模型（ASM）和标准k-ε涡粘性模型（k-εEVM）的建筑物周围湍流数值预测的准确性。在这里，表面安装的立方体被用作建筑模型。通过与实验数据的比较，评估了这四种湍流模型的精度和相对性能。通过比较速度矢量、平均压力系数、湍流能量、湍流产生和法向应力分量等的分布，检验了这些湍流模型给出的结果之间的差异。 关键词:1996年，计算，气流，建筑，湍流，精度，性能，比较，风洞，实验，模型试验:研讨会论文，亚特兰大，佐治亚州，1996年

The accuracy of numerical predictions based on large eddy simulation (LES), the differential stress model (DSM), the algebraic stress model (ASM), and the standard k-epsilon eddy viscosity model (k-epsilon EVM) is examined for the turbulent flow around a building. Here, a surface-mounted cube is used as the model of a building. The accuracy and relative performance of these four turbulence models are assessed by comparing them with experimental data. The differences between the results given by these turbulence models are examined by comparing the distribution of velocity vectors, mean pressure coefficients, turbulence energy, turbulence production, and normal stress components, etc.KEYWORDS: year 1996, calculating, air flow, buildings, turbulent flow, accuracy, performance, comparing, wind tunnels, experiment, models
