A fourth order sharp immersed method for the incompressible Navier-Stokes equations with stationary and moving boundaries and interfaces
Xinjie Ji, Changxiao Nigel Shen, Wim M. van Rees
We propose a fourth order Navier-Stokes solver based on the immersed interface method (IIM), for flow problems with stationary and one-way coupled moving boundaries and interfaces.…

A sharp immersed method for 2D flow-body interactions using the vorticity-velocity Navier-Stokes equations
Xinjie Ji, James Gabbard, Wim M. van Rees
Immersed methods discretize boundary conditions for complex geometries on background Cartesian grids. This makes such methods especially suitable for two-way coupled flow-body prob…
