本文建立了一个涡轮冷气掺混的数学模型并将其应用到气冷涡轮的 S2 流面计算中。根据该模型推导出了考虑冷气掺混时相对坐标系下的气动热力学方程组。通过掺混流函数的引入建立了计及冷气掺混的 S2 流面计算方法。计算结果表明了本文模型的合理性与算法的可行性
In this paper, a mathematical model of turbine air-cooled blending is established and applied to the calculation of S2 flow surface of an air-cooled turbine. Based on this model, the aerodynamic thermodynamic equations in the relative coordinate system considering cold air blending are derived. Through the introduction of mixed flow function, a calculation method of S2 flow surface considering the cold air blending is established. The calculation results show the rationality of this model and the feasibility of the algorithm
