| 摘 要： | 基于室内空调环境紊流试验台,实测该流场中具有代表性的16个点的速度,采用数值计算软件FLUENT,分别运用标准k-ε,RNGk-ε模型,realizablek-ε模型对该流场进行数值模拟,通过实验与数值模拟相互对照,对比分析三种紊流模型的流场与实验流场的吻合度,验证了RNGk-ε模型对实验流场的相对适应性,为相关流场的数值计算提供参考。

| Abstract: | Based on the testbed of the turbulence model in the indoor air-conditioning environment ,the pa-per measures the speeds in the 16 spots typical of the flow distribution ,uses the FULET numerical calcu-lation software and conducts the numerical simulation of the flow distribution by applying standard k-ε, RNGk-εand realizablek-εmodels .Then ,it analyzes the consistency between the three kinds of flow distri-butions in the model and the experiment by comparing their respective data .T he study validates the rela-tive adaptability of RNG k-εmodel to the experimental flow distribution ,thus providing reference for nu-merical simulation of similar flow distributions . |
