摘要
The optimization of radial and mixed flow turbine design, based on simple one-dimensional aerodynamic principles, is described. The objective is to minimize energy losses by reducing the inlet and exit velocities of the rotor. The procedure is based on the specification of a loading coefficient. Previous work has shown that turbines of this type have loading coefficients that lie in a narrow band, and so suitable values can be readily determined. A more detailed specification of losses is unnecessary for the optimization. Optimizations are described for zero and non-zero inlet blade angles, and zero, positive and negative exit swirl conditions.
