A Lagrangian free-stream boundary condition for weakly compressible smoothed particle hydrodynamics
Shuoguo Zhang, Wenbin Zhang, Chi Zhang +1
This paper proposes the first free-stream boundary condition in a purely Lagrangian framework for weakly-compressible smoothed particle hydrodynamics (WCSPH). The boundary conditio…
Pattern formation in weakly damped parametric surface waves driven by two frequency components
Wenbin Zhang, Jorge Vinals
A quasi-potential approximation to the Navier-Stokes equation for low viscosity fluids is developed to study pattern formation in parametric surface waves driven by a force that ha…
Pattern formation in weakly damped Faraday waves
Wenbin Zhang, Jorge Vinals
We present a theoretical study of nonlinear pattern formation in parametric surface waves for fluids of low viscosity, and in the limit of large aspect ratio. The analysis is based…
Square Patterns and Quasi-patterns in Weakly Damped Faraday Waves
Wenbin Zhang, Jorge Vinals
Pattern formation in parametric surface waves is studied in the limit of weak viscous dissipation. A set of quasi-potential equations (QPEs) is introduced that admits a closed repr…
Secondary Instabilities and Spatiotemporal Chaos in Parametric Surface Waves
Wenbin Zhang, Jorge Vinals
A two dimensional model is introduced to study pattern formation, secondary instabilities and the transition to spatiotemporal chaos (weak turbulence) in parametric surface waves.…
Narrow band noise as a model of time-dependent accelerations: study of the stability of a fluid surface in a microgravity environment
Jaume Casademunt, Wenbin Zhang, Jorge Vinals +1
We introduce a stochastic model to analyze in quantitative detail the effect of the high frequency components of the residual accelerations onboard spacecraft (often called g-jitte…
