Calibration of a meanline centrifugal pump model using evolutionary algorithms

摘要: AbstractA one-dimensional meanline prediction code suitable for performance of small-to-medium size turbopumps (3–40 kW) is developed, which able to predict both on and off-design a turbopump given the loss diffusion system at design point. This model then calibrated against experimental data using an optimization technique. Due rapidity computations, single-objective evolutionary algorithm used calibration in order obtain wide exploration search space. Accuracy finally demonstrated by means comparison between predicted actual pump performance.
