본 발명은 곡률을 일정하게 형성하여 손실이 적은 배기덕트에 관한 것으로, 터빈으로부터 배출되는 유체를 배출시키는 곡관으로 형성된 배기덕트에 있어서, 유체가 유입되는 입구, 유입된 유체를 출구로 유도하는 몸체, 및 유체가 배출되는 출구를 포함하고, 몸체의 내주면의 곡률 및 외주면의 곡률이 일정하거나 몸체의 내주면의 곡률의 변화 및 외주면의 곡률의 변화가 일정한 것을 특징으로 함으로써 배기덕트의 형상을 개선하여 유동의 박리를 감소시켜 유동손실을 줄일 수 있다.

    The present invention relates to an exhaust duct having a constant curvature to reduce loss. The exhaust duct comprises a curved pipe for discharging fluid discharged from a turbine. The exhaust duct includes: an inlet through which the fluid is introduced; a body that guides the introduced fluid into an outlet; and the outlet through which the fluid is discharged. The curvature of the inner circumferential surface of the body and the curvature of the outer circumferential surface of the body are constant, or a change in the curvature of the inner circumferential surface of the body and a change in the curvature of the outer circumferential surface of the body are constant, thereby improving the shape of the exhaust duct and reducing flow separation to reduce flow loss.
