摘　　要：为分析某燃气轮机低压模化试验对燃烧室试验结果的影响,利用ANSYS CFX软件,对某型燃气轮机燃烧室进行了实际工作参数及模化工作参数下的数值模拟对比分析研究。研究结果表明:对比实际工作参数,燃烧室在等容积流率模化试验条件下,由于保证了流场速度相同,故燃烧室速度场变化较小;但燃烧压力与质量流量降低会导致火焰长度缩短,出口温度不均匀程度偏好,火焰筒壁温偏低。In order to analyze the influence of a certain gas turbine low-pressure modeling test on the combustion chamber test results,the ANSYS CFX software was used to conduct a comparative analysis under the actual working parameters and the modeling working parameters.The results show that compared with the actual working parameters,the velocity field of combustion chamber changes little under the condition of constant volume flow rate in the modeling test,due to the same flow velocity.However,the decrease of combustion pressure and mass flow leads to a shorter flame length,uneven exit temperature,and relatively low wall temperature of flame cylinders.
