A cut-cell method for fluid-structure interaction on adaptive Cartesian meshes

A new immersed boundary method to simulate the interaction of a viscous fluid with rigid boundaries is presented. The method is based on a strictly conservative Cartesian cut-cell scheme and accounts accurately for the fluid forces exerted on the solid boundaries. The boundaries are represented using a signed-distance function by which one or multiple immersed bodies can be tracked efficiently....

Cartesian Cut-Cell Method with Local Grid Refinement for Wave Computations

Sound generation from a vibrating circular piston is a classical acoustic problem. The goal of this paper is to simulate numerically the sound radiation produced by oscillating baffled pistons, using both linear and nonlinear model, and to consider the interplay between wave propagation and geometric complexities. The linear solution, based on the linear Euler equations, will be compared to the...

A Cartesian cut cell method for rarefied flow simulations around moving obstacles

For accurate simulations of rarefied gas flows around moving obstacles, we propose a cut cell method on Cartesian grids: it allows exact conservation and accurate treatment of boundary conditions. Our approach is designed to treat Cartesian cells and various kind of cut cells by the same algorithm, with no need to identify the specific shape of each cut cell. This makes the implementation quite...
