| 摘 要： | 对燃气轮机排气引射装置进行了三维数值模拟，采用非结构网格、Realizable κ-ε湍流模型求解三维N-S方程组，得到了全流场速度、压力、温度等的分布情况，并进行了详细分析。结果表明所采用的数值模拟方法较为准确，能充分反映排气引射装置的流场发展情况。对排气引射装置设计具有指导意义。

| Abstract: | A three-dimensional numerical simulation on the exhaust injector of gas turbines is carried out in this paper.Unstructured grids and realizable k-turbulent model are used to solve N-S equation,and the velocity,pressure and temperature distribution in the flow field are obtained,with detailed analyzing.The result shows that the numerical simulation method is accurate and can well reflect the flow field development of exhaust injector.The result can be referenced for the design of the exhaust injector. |
