Compared to non-cavitating flow, cavitating flow is much complex owing the numerical difficulties caused by cavity generation and collapse. In this paper, around a NACA66 hydrofoil studied numerically with particular emphasis on understanding cavitation structures shedding dynamics. Large Eddy Simulation (LES) was coupled homogeneous model calculate pressure, velocity, vapor volume fraction vorticity hydrofoil. The predicted dynamics behavior, including growth, break-off collapse downstream,...
Cavitating turbulent flow around hydrofoils was simulated using the Partially-Averaged Navier–Stokes (PANS) method and a mass transfer cavitation model with maximum density ratio (ρl/ρv,clip) effect between liquid vapor. The predicted cavity length thickness of stable cavities as well pressure distribution along suction surface NACA66(MOD) hydrofoil compare experimental data when actual (ρl/ρv,clip = 43391) at room temperature. unsteady patterns their evolution Delft twisted were then...
This study presented a multi-scale Eulerian–Lagrangian approach to simulate cavitating turbulent flow around Clark-Y hydrofoil the bubble dynamics. A large eddy simulation was coupled with volume of fluid method capture vapor volumes in an Eulerian analysis. Micro-scale Lagrangian bubbles were then tracked by solving compressible Rayleigh–Plesset equation and motion equation. Gaussian kernel function used model interactions between field two-way algorithm. The predictions give satisfactory...
This paper investigates the effect of gap size on inception tip leakage vortex cavitation (TLVC) with a hybrid Eulerian–Lagrangian model. Good agreement is achieved between simulation results and experimental data for velocity distributions around TLV, bubble motion, its oscillations. It found that minimum pressure criterion not accurate enough prediction TLVC due to significant fluctuation increased concentration nuclei in TLV core region. The noted be non-negligible factor, while...
This paper investigates the noise reduction performance of biomimetic hydrofoils with wavy leading edge and corresponding mechanisms. We employ Large Eddy Simulation (LES) approach permeable Ffowcs Williams-Hawkings (PFW–H) method to predict cavitation around baseline hydrofoils. The results show that can effectively reduce high-frequency noise, but has little effect on low-frequency noise. Further analyses discussions deal main source for is cavity volume acceleration, while it. sources,...
The effects of CO₂-water-rock interactions on the mechanical properties shale are essential for estimating possibility sequestrating CO₂ in reservoirs. In this study, uniaxial compressive strength (UCS) tests together with an acoustic emission (AE) system and SEM EDS analysis were performed to investigate microstructural changes black shales different saturation times (10 days, 20 days 30 days) water dissoluted gaseous/super-critical CO₂. According experimental results, values UCS, Young's...
The flow around submerged canopy patches with finite sizes plays a critical role in the sediment deposition and vegetation evolution. In this study, patch was modeled as porous array diameter D height h consisting of N rigid cylinder elements d exposed to fully developed turbulent open channel depth H. High-resolution numerical simulations were conducted investigate effects density (0.021 ≤ Φ = Nd2/D2 1) on mean instantaneous fields three-dimensional coherent structures by fixing aspect...
In the present study, a two-way coupling Eulerian–Lagrangian approach is developed to assess cavitation erosion risk in an axisymmetric nozzle. Macroscopic structures are simulated using large eddy simulation along with volume of fluid method. The compressible Rayleigh–Plesset equation and bubble motion introduced resolve microscopic dynamics. calculated results agree favorably experimental data can capture more flow details, which associated potential risk. Based on information multi-scale...
