摘要(Abstract):

应用计算流体力学软件Fluent建立了安全阀三维可压缩流场计算模型。采用标准κ-ε和Realizable κ-ε两种湍流模型,并将两个模型的计算结果与验证实验的测试数据进行对比,确定了更合适的模型。并对安全阀的流场形态和工作特性进行了分析。
Fluent is used to built three-dimensional numerical model of internal flow of pressure relief valve(PRV).Standard κ-ε and Realizable κ-ε turbulent model are adopted,and different simulation results are compared with experimental data,to make sure which one is better.Flow characteristic analysis is performed by analyzing simulation results.
