Surrogate‐Assisted Multi‐Objective Optimization of an Axial‐Flow Ventricular Assist Device Rotor Using CFD , Hybrid Surrogates, Sobol Analysis, and MOPSO

ABSTRACT Background This study presents a surrogate‐assisted workflow for multi‐objective optimization of an axial‐flow ventricular assist device (VAD) rotor using 4809 steady‐state CFD simulations spanning six geometric variables. Methods Repeated learning‐curve analysis and bla...

Tolerance-aware robust ranking of ventricular assist device rotor designs using strict feasibility and percentile-based criteria

Manufacturing variability can alter the hydraulic and hemocompatibility performance of a ventricular assist device (VAD) rotor even when the nominal design is computationally optimal. This study presents a surrogate-assisted robust-design workflow for a rotary VAD using a CFD-der...
