Collective lattice excitations in the dynamic route for melting hydrodynamic two-dimensional crystals

Physical Review Research
Liquid surface stiffness generates stable Faraday wave (FW) patterns, known as hydrodynamic crystals, which form resonant FW lattices composed of discrete harmonics and subharmonics under monochromatic driving.

Evaluation of hydrodynamic forces on turbine ring gate during emergency shutdown process

Advances in Mechanical Engineering, 2015
This work uses numerical methods to investigate the hydrodynamic forces that act on a turbine ring gate during emergency shutdown. Accurately predicting the hydrodynamic forces on such gates is important because the forces constitute a design criterion ...

Hydrodynamic simulations with radiative surface

, 2013
We solve the equations of radiation hydrodynamics to compute the time evolution toward one-dimensional equilibrium solutions using ageneralized Kramers opacity, κ=κ0 ρa Tb, with adjustable prefactor κ0 and exponents a and b on density ρ and temperature T, respectively.

A Runoff‐On‐Grid Approach to Embed Hydrological Processes in Shallow Water Models

Water Resources Research
Catchment‐scale hydrological models encountered dichotomies with the numerical hydrodynamic models when describing surface routing process. We propose a new modeling framework, the so‐called “Runoff‐On‐Grid” approach, for embedding distributed process ...

Hydrodynamic lubrication of rough surfaces

, 2005
Interacting surfaces are frequently found in mechanical systems and components. A lubricant is often added between the surfaces to separate them from mechanical contact in order to increase life and performance of the contacting surfaces. In this work various aspects of hydrodynamic lubrication are investigated theoretically.

Numerical study on the supercavitating flow around an underwater high-speed projectile near the unsteady free surface

AIP Advances
When a high-speed projectile navigates underwater near the surface, the unsteady free surface changes the surrounding flow velocity and pressure distribution, which affects the supercavitating flow pattern and hydrodynamic characteristics. Therefore, the
