Design Optimization of Centrifugal Pumps to Improve the Performance and Operating Stability

Surrogate-based design optimization techniques were applied to enhance the performance and reliability of centrifugal pumps. First, the objective functions to be minimized, along with the equality and inequality constraints within the design space, were defined. The design variables and design space were selected through a parametric study and global sensitivity analysis. Initial sample designs were chosen using Design of Experiments (DOE) techniques. A surrogate model was then constructed based on the objective and constraint function values obtained. Pareto-optimal solutions were derived using a Multi-Objective Genetic Algorithm (MOGA), and the accuracy of these solutions was validated through numerical simulations.
