Immersed Boundary Methods
Cartesian-grid solvers for complex and moving geometries
Overview
We develop sharp-interface immersed boundary methods that allow accurate simulation of flows over complex geometries without body-fitted meshes. By combining ghost-cell reconstruction with high-order Cartesian-grid solvers, the approach maintains near-boundary accuracy while enabling straightforward parallelisation. Current work extends the framework to moving and deforming boundaries.
