TABLE S1: Cd(Re) CORRELATION DATA (SUPPLEMENTARY)

This dataset supports the development and validation of a unified micro–meso–macro modeling framework for high-bandwidth electrohydraulic actuation. It includes CFD-simulated discharge coefficient (Cd) values across 112 Reynolds number cases (Re = 100–5000), experimentally validated frequency response data (magnitude and phase up to 800 Hz), closed-loop bandwidth measurements (650 Hz at −3 dB), and natural frequency results (950 Hz). Data also covers system performance under varying operating pressures (15–21 MPa) and inertial loads (1.5–2.5 kg). Tables summarize model parameters, transient inertia effects (equivalent fluid mass: 12.9 kg), and ablation studies showing errors from neglecting Cd(Re) or fluid inertia. All results are within ±3.2% uncertainty, with 96.8% prediction accuracy. This dataset enables reproducibility of multi-scale dynamics coupling micro-scale flow physics with macro-scale control behavior.
