A 2D embedded-boundary algorithm for convection problems is presented. A moving body of arbitrary boundary shape is immersed in a Cartesian finite-volume grid, which is fixed in space. The boundary surface is reconstructed in such a way that only certain fluxes in the immediate neighbourhood indirectly accommodate effects of the boundary conditions valid on the moving body. Over the majority of the domain, where these boundary conditions have "no" effect, the fluxes are computed using standard schemes. Examples are given to validate the method.
