Abstract A comprehensive study on interpolation schemes used in overset grid techniques is here presented. Based a literature review, numerous are implemented, and their robustness, accuracy, performance assessed. Two code verification exercises performed for this purpose: 2D analytical solution of laminar Poiseuille steady flow; an intricate manufactured turbulent flow case, characteristic bou...

We use the energy method to study well-posedness of initial-boundary value problems approximated by overset mesh methods in one and two space dimensions for linear constant-coefficient hyperbolic systems. show that dimension, both scalar equations systems equations, problem where domain partially oversets another is well-posed when characteristic coupling conditions are used. If a system cannot...

The capability of path tracking largely determines the operational efficiency deep-sea mining vehicles. In this paper, relationships vehicle–sediment mechanical interaction were obtained by sinkage and shear tests. Then, an overset grid method was used to establish computational fluid dynamics (CFD) model vehicle, spatial hydrodynamic distribution calculated in different motion states. Based on...

A high-order finite-difference algorithm is proposed in the aim of LES and CAA applications. The subgrid scale dissipation is performed by the explicit high-order numerical filter used for numerical stability purpose. A shock-capturing non-linear filter is also implemented to deal with compressible discontinuous flows. In order to tackle complex geometries, an overset-grid approach is used. Hig...

Advances in automation and robustness of the X-rays approach to domain connectivity for overset grids are presented. Given the surface definition for each component that makes up a complex configuration, the determination of hole points with appropriate hole boundaries is automatically and efficiently performed. Improvements made to the original X-rays approach for identifying the minimum hole ...
