Frequency characteristics of liquid hydrogen cavitating flow over a NACA0015 hydrofoil

•Unsteady LH2 cavitation over an 3D hydrofoil is modeled based on LES.•Frequency characteristics of LH2 cavitation cloud are specially analyzed.•Strouhal number is much lower than water at σ/2α > 2, while same at σ/2α
