| 摘 要： | 本文在S_2流面流函数线松弛解法的基础上提出了考虑冷气掺混的涡轮气动计算方法,阐述该方法对直接计入质量和能量掺混而间接计入动量掺混的影响,通过一个算例证实了该方法的可行性和必要性。

| Abstract: | Based on a line-relaxation algorithm of stream function for the flow along S_2 stream surface, this paper presents an aerodynamic calculation method for a gas turbine with cooling air mixing.The mass flow mixing and the energy mixing of the cooling air with the main gas flow are taken into account directly with the momentum loss resulting from the said mixing being assessed indirectly. Through a calculation example is demonstrated the feasibility and advisability of such a method. |
