A multi-scale approach for wall-bounded WCSPH--RANS simulations
Feng Wang, Nikolaus Adams, Xiangyu Hu
Achieving sufficient near-wall resolution remains challenging for wall-bounded turbulence simulations using weakly compressible smoothed particle hydrodynamics (WCSPH), as local pa…
An efficient implementation of the bidirectional buffer: towards laminar and turbulent open-boundary flows
Feng Wang, Xiangyu Hu
To effectively handle flows characterized by strong backflow and multiple open boundaries within particle-based frameworks, this study introduces three enhancements to improve the…
On zero-order consistency residue and background pressure for the conservative SPH fluid dynamics
Feng Wang, Xiangyu Hu
As one of the major challenges for the conservative smoothed particle hydrodynamics (SPH) method, the zero-order consistency issue, although thought to be mitigated by the particle…
A weakly compressible SPH method for RANS simulation of wall-bounded turbulent flows
Feng Wang, Zhongguo Sun, Xiangyu Hu
This paper presents a Weakly Compressible Smoothed Particle Hydrodynamics (WCSPH) method for solving the two-equation Reynolds-Averaged Navier-Stokes (RANS) model. The turbulent wa…
