Numerical analysis on hydrodynamic performance and hydrofoil optimization for amphibious vehicles

The Physics of Fluids, 2023
A numerical approach is established to study the hydrodynamic performance using an amphibious transport vehicle (ATV) as a research object. Numerical calculation based on the Reynolds average Navier–Stokes method is studied in terms of first layer grid ...

Vortex dynamics and hydrodynamic performance enhancement mechanism in batoid fish oscillatory swimming

Journal of Fluid Mechanics, 2021
The effects of chordwise deformation and the half-amplitude asymmetry on the hydrodynamic performance and vortex dynamics of batoid fish have been numerically investigated, in which the two parameters were represented by the wavenumber ($W$) and the ...

Hydrodynamic performance of slender swimmer: effect of travelling wavelength

Journal of Fluid Mechanics, 2022
The impact of Strouhal number St (= 0.1–1.0), Reynolds number Re (= 50–2000) and dimensionless wavelength λ (= 0.5–2.0) on the hydrodynamic performance of a travelling wavy foil of a constant length is extensively investigated.

Comparison of the hydrodynamic performance of front and rear-stator pump-jet propulsors in an oblique wake under the cavitation condition

The Physics of Fluids, 2022
Pump-jet propulsors, which exhibit high efficiency and low noise, are widely used in underwater vehicles. In a marine environment, a nonuniform wake and an oblique flow affect a propulsor's hydrodynamic force.
