acousticHelmholtzFoam: an MPI-parallel unstructured finite-volume solver for frequency-domain acoustics in heterogeneous two-phase media with perfectly matched layers
Chuanchao Xu, Jun Liu, Dieter Bothe +1
acousticHelmholtzFoam is an OpenFOAM application that computes time-harmonic acoustic pressure fields in heterogeneous gas-liquid media on unstructured polyhedral meshes. The compl…
High-order staggered Lagrangian hydrodynamics (II) : the artificial viscosity and hourglass control algorithm
Zhiyuan Sun, Jun Liu, Pei Wang
In this article, we investigate the artificial viscosity and hourglass control algorithms for high-order staggered Lagrangian hydrodynamics(SGH), as proposed in~\cite[Sun et al., 2…
A Thermodynamically Consistent High-Order Framework for Staggered Lagrangian Hydrodynamics
Zhiyuan Sun, Jun Liu, Pei Wang
We present a consistent high-order staggered Lagrangian hydrodynamics framework designed to reconcile an underlying disparity in existing curvilinear formulations: the mismatch bet…
The initial acceleration of a buoyant spherical bubble revisited
Dieter Bothe, Jun Liu, Pierre-Etienne Druet +3
An analytical derivation of the buoyancy-induced initial acceleration of a spherical gas bubble in a host liquid is presented. The theory makes no assumptions further than applying…
A residual-based non-orthogonality correction for force-balanced unstructured Volume-of-Fluid methods
Jun Liu, Tobias Tolle, Tomislav Maric
Non-orthogonality errors in unstructured Finite Volume methods for simulating incompressible two-phase flows may break the force-balanced discretization. We show that applying the…
Inconsistencies in Unstructured Geometric Volume-of-Fluid Methods for Two-Phase Flows with High Density Ratios
Jun Liu, Tobias Tolle, Davide Zuzio +3
Geometric flux-based Volume-of-Fluid (VOF) methods are widely considered consistent in handling two-phase flows with high density ratios. However, although the conservation of mass…
