In accordance with large temperature gradient in multi-stage turbine channel,an aerothermodynamic method is proposed for varying specific heat solution of S 2 surface to consider precisely the effect of temperature variation on the computed results.

• 针对在多级涡轮流道中沿流动方向燃气温度变化较大这一特点，为了准确反映出温度变化对气动热力计算结果的影响，提出了一种考虑变比热影响的S2流面的气动热力计算方法。
