An accurate moving boundary formulation in cut-cell methods
Journal of Computational Physics, 2013A cut-cell method for Cartesian meshes to simulate viscous compressible flows with moving boundaries is presented. We focus on eliminating unphysical oscillations occurring in Cartesian grid methods extended to moving-boundary problems. In these methods, cells either lie completely in the fluid or solid region or are intersected by the boundary.

An adaptive cut‐cell method for environmental fluid mechanics
International Journal for Numerical Methods in Fluids, 2008AbstractIn this work we present a numerical method for solving the incompressible Navier–Stokes equations in an environmental fluid mechanics context. The method is designed for the study of environmental flows that are multiscale, incompressible, variable‐density, and within arbitrarily complex and possibly anisotropic domains.

An Ocean Model Using Cut-Cell Method
OCEANS 2006 - Asia Pacific, 2006An ocean model using cut-cell method has been developed to simulate the flow field around the complicated topographic feature in the three dimensions. The finite-volume method is applied for the accuracy of the mass- and momentum-conservations. Formulations for the finite difference are given for the advection, pressure and viscous terms, including the

Cartesian cut-cell method for axisymmetric separating body flows
AIAA Journal, 1999A method for the calculation of unsteady, axisymmetric compressible flows involving both fixed and separating bodies is presented. The method uses a Cartesian cut-cell mesh approach and high resolution upwind finite volume scheme. A stationary background Cartesian mesh is generated on the computational domain with complex solid geometries represented ...

Consistent Discretization Methods for Reservoir Simulation on Cut-Cell Grids
SPE Reservoir Simulation Conference, 2023Abstract Discretization methods have been developed to accompany a novel cut-cell gridding technique for reservoir simulation that preserves the orthogonality characteristic in the lateral direction. A major drawback of the cut-cell gridding method is that polyhedral cells emerge near faults that have relatively small volumes.

A cut cell method for the 3D simulation of Crookes radiometer
AIP Conference Proceedings, 2014Devices involved in engineering applications, such as vacuum pumps or MEMS, may be made of several moving parts. This raise the issue of the simulation of rarefied gas flow around moving boundaries. We propose a simple process, known as cut cell method, to treat the motion of a solid body in the framework of the deterministic solving of a kinetic ...

A Cartesian cut-cell method for sharp moving boundaries
20th AIAA Computational Fluid Dynamics Conference, 2011The extension of a three-dimensional, strictly conservative Cartesian cut-cell based method to stimulate flows bounded by complex geometries with moving parts like in-cylinder flows is presented. The method handles complex geometric details of three-dimensional technical objects such as sharp edges and acute-angled features, which may lead to cells ...

Simulating the Linearly Elastic Solid–Solid Interaction with a Cut Cell Method
International Journal of Computational Methods, 2017In this work, a cut cell-based sharp interface method is developed to deal with the interaction between linearly elastic solids in Eulerian framework. The material interface is represented by cut faces, and evolved by level set equation. Finite volume scheme is applied and strong coupling is achieved by using the Riemann solver for linearly elastic ...
