Multi-Objective Optimization of Blood-Pump with Conical Spiral Groove Bearings

摘要：

Multi-Objective Genetic Algorithm (MOGA) optimization was developed to realize a smaller and higher efficiency blood pump without hemolysis. The hydrodynamic efficiency, impeller outer diameter, and shear velocity were chosen as GA objective functions. The measured pump performance of the GA optimized pump was acceptable as a blood pump. And unsteady RANS calculations showed that the hemolysis can be suppressed in the GA optimized pump by eliminating higher shear velocity region in flow. As the result of the present study the GA optimization is found to be effective for the design of blood pumps.
