Beschreibung
Zusammenfassung:	The invention discloses a design method of a fluid passage of an air exhausting device of a combustion gas turbine. The design method of the fluid passage of the air exhausting device of the combustion gas turbine is used for reducing the pressure loss of the fluid passage between a circular or a circular ring-shaped air inlet and a rectangular air outlet at the perpendicular state, and comprisesthe steps of uniformly dividing the air inlet into 2n fan-shaped or fan ring-shaped air inlet units, uniformly dividing the air outlet into air outlet units with the same number of the air inlet units, and connecting the air inlet units and the air outlet units so as to form 2n fluid passage units, wherein each fluid passage nut comprises a transition section, a diffusion section and a convergencesection. According to the design method of the fluid passage of the air exhausting device of the combustion gas turbine provided by the invention, the fluid passage is designed to be of a split typestructure, and the 2n fluid
