A new technique is proposed for maintaining conservation across block boundaries when using a Chimera grid embedding method for incompressible viscous flows. The chimera method is used to connect embedded or patched grids together by interpolating information across the grid boundaries. This technique has been found to be a useful tool for simplifying the grid generation process for complex configurations and has proven to be an effective means of refining grids in areas of high gradients. When first using this technique for incompressible flows that incorporate some type of iterative pressure/velocity coupling scheme, errors resulted along the interpolated boundary. A new method was developed that maintains continuity and yields a smooth solution across the linking boundaries. Calculations performed for submarine configurations clearly demonstrated the flexibility and effectiveness of the present Chimera Reynolds Averaged Navier Stokes (RANS) method for incompressible turbulent flows around complex configurations.
