| Abstract: |
| On the basis of conditional extreme value of non-linear mathematical programming,the optimum design method was applied in the design on geometric parameters and one-dimension pneumatic thermodynamics of axial or radial turbine and compressor. The complete physical model and mathematical expressions were developed for axial or radial turbine optimum design. By using the SUMT method, the extreme value problem with inequality constraint conditions was turned into optimum design problem without constraints, and was calculated by DFP conjugate direction method. An example was provided to one-dimension optimum design of axial or radial turbine. |
