The present study deals with the theoretical analysis required for the design of a vaneless nozzle for an axial turbine. This vaneless has a turbine scroll in a vertical position to the turbine rotor axis. The working fluid flows from the inlet to the scroll perpendicular to the rotor axis, thus resulting in having an angular momentum to the axis. The flow from the scroll expands in an inducer section, making a swirl flow under the condition of constant angular momentum. Then the flow is turned to the direction of the turbine axis and goes to the turbine blades. The paper makes clear the existence of the flow which is satisfied with the condition that the outlet angle is constant and the circulation is constant respectively in the direction of the radius at the outlet of the vaneless nozzle.
