Turbine Design

“IRIS” is a computerized design and structural optimization system capable of generating all the major hydraulic and mechanical design parameters of high head pump/turbines from limited input data. The program will size the unit and select the proper hydraulic passage configuration according to performance requirements and optimize the dimensions of all the major components, generate command tapes used by a numerically controlled flame cutter, estimate cost, and issue manufacturing process planning. It also generates finite element models for the “in depth” analysis of critical components.

Turbine Design

Recently, a computer-aided interactive design system has been used for turbine design. The blade-to-blade flow program incorporated in the system is required to have short run times, robustness, and no limitations. The Denton time-marching code is attractive as it is fast and can handle mixed subsonic–supersonic flows. The Denton new scheme was published in 1982 and improvements were achieved in run times and entropy conservation. In this paper, code control variables are calibrated from the user’s point of view. Factors affecting computing costs and accuracy are investigated, and the “know-how” necessary to operate the code efficiently is discussed. Comparisons of calculated and experimental results are presented in part II.
