A high-order ghost-point immersed boundary method coupled with auxiliary differential equations for time-domain impedance walls

A ghost-point immersed boundary method is coupled with auxiliary differential equations to impose a locally-reacting impedance condition on a wall that does not conform to a Cartesian grid, in the framework of the linearized Euler equations. The ghost-point reconstruction follows the normal-stencil approach: an ellipti...
