✦ Synopsis

A rigorous and robust numerical procedure to treat surface reaction boundary conditions for finite-volume schemes in unstructured meshes is presented. The procedure is applicable to arbitrary cell topologies and multistep finite-rate surface reactions of arbitrary complexity. The accuracy of the numerical procedure has been verified by systematically comparing solutions obtained using unstructured meshes with perfectly orthogonal meshes for both two-dimensional and three-dimensional geometries. Validation results presented for gallium arsenide growth in a full-scale commercial metal organic-chemical vapor-deposition reactor, exhibit excellent match with experimental data.

## Abstract This paper describes a central difference scheme for the prediction of flows with an interface. The interface is captured rather than tracked and the key to the current approach is a correction to the hydrostatic pressure. The correction enables the scheme to evaluate pressures at cell
