摘要/Abstract

摘要： 为了实现计算机虚拟试验,在所建立基于混合物分数的分区模型和早期针对某涡轮试验台主体试验系统开展的三十八组件系统数值研究的基础上,结合调台试验开展了算法改进和仿真研究。对燃烧装置及影响燃烧过程元件仿真结果的分析表明,仿真全面揭示了空气流量主控调节阀、放气旁路调节阀、涡轮进口调节阀以及燃油流量对燃烧装置状态参数的动态影响过程,所获得的规律性结论为实际的调台试验提供了指导,显示了有限体积模型体系在管路系统仿真领域的工程应用价值和数值拓展潜力。

Abstract: On the basis of the mixture fraction-based partition model and the previous 38-component system numerical research on a turbine test rig main test system, this paper conducts algorithm improvement and simulation research based on a rig regulating experiment in order to realize computer virtual test. Analysis on simulation results of the combustion device and those components which affect combustion process shows that the simulation fully reveals the dynamic influence process of main air-flow-rate regulator valve, exhaust-bypass regulator valve, turbine-inlet regulator valve and fuel-oil flow rate on various state parameters of combustion device, and the regularity conclusions obtained are used to provide guideline for actual rig regulating test. It also demonstrates the engineering application value and numerical extension potential of the finite volume model system in the field of pipeline system simulation.

Key words: Turbine test rig；Combustion device；Modularization modeling；System dynamic simulation
