OPTIMIZED DESIGN METHOD FOR RADIAL-FLOW-TYPE HYDRAULIC TURBINE

摘要

An optimized design method for a radial-flow-type hydraulic turbine comprises a unitary thermal optimization design method, a three-dimensional modeling method of a through-flow part and a complete machine optimization method. The complete machine optimization method comprises the following steps: a nozzle guide blade and impeller blade parameterization step, a concerted evolution genetic algorithm, an adaptive approximate model and a CFD auto-call algorithm. This design method effectively reduces the calculation amount.
