The aerodynamic characteristics of the exhaust system have an important bearing on the economic aspects of the marine gas turbine. Tee exhaust volute is an important component of the exhaust system. The design of turbine exhaust volutes must take into account the structural demands of the gas turbine, the layout of the exhaust system as a whole in the engine room and the hull as well as its overall dimension requirements. This paper descusses the design principles of exhaust volutes. Given the hub-tip ratio d(ind1)/D(ind1) of turbine exit (volute entry), a method is developed to rationally select the axial length L and radial width B. The selection of an annular diffuser and the relevant parameters along with the coordination of diffuser and collector are analyzed. On the basis of an analysis of experimental data the basic design criteria of exhaust volutes are proposed. (Wassmann)
