“…Interpolation is used to transfer data between two mesh systems (or multiple mesh systems if multiple bodies are considered). This method has been adopted by Jia and Nakamura [20] for simulating three bodies inside a fluid, by Chen and Liu [5] for studying the flow induced by a ship in harbor, and by Zhang and Wang [40] for simulating flow and pressure distribution around a cylinder and an airfoil. Since the remeshing is not required for a rigid body in the overlapped mesh system, it is more computationally efficient.…”

“…The method is very general and can model both the bottom topography and shorelines in addition to the physical structures. A more detailed description of the chimera domain decomposition approach is given in Chen and Chen (1998) and Chen and Liu (1999).…”

A new three-dimensional potential flow numerical method has been developed to study wave diffraction around compound coastal structures. This new method is based on a multi-block finiteanalytic scheme. A chimera domain decomposition technique is used to model complex geometry and to connect overlapped grids by interpolating information across block boundaries. Calculations were performed for three examples, including a harbor entrance, a single breakwater, and a combined breakwater and large floating platform, to illustrate the flexibility and effectiveness of the present method.

“…They compared their data with Ekkad and Han (1997) Hubbard and Chen (1994) and Chen and Chen (1998) were employed to eliminate the unphysical mass source resulting from the interpolation errors between the chimera grid blocks. More detailed descriptions of the chimera RANS method were given in Chen and Chen (1998) and Chen and Liu (1999).…”

Numerical predictions of three-dimensional flow and heat transfer are presented for a two-pass square channel with 90 parallel ribs. Square sectioned ribs were employed along the one side surface. The rib height-to-hydraulic diameter ratio (e/Dh) is 0.125 and the rib pitch-to-height ratio (P/e) is 10. The computation results were compared with the experimental data of Ekkad and Han (1997) at a Reynolds number (Re) of 30,000.A multi-block numerical method was used with a chimera domain decomposition technique. The finite analytic method solved the Reynolds-Averaged Navier-Stokes equation in conjunction with a near-wall second-order Reynolds stress (secondmoment) closure model, and a two-layer k-e isotropic eddy viscosity model. Comparing the second-moment and two-layer calculations with the experimental data clearly demonstrated that the rib turbulators and the 180 sharp turn of the channel produced strong non-isotropic turbulence and heat fluxes, which significantly affected the flow fields and heat transfer coefficients. The near-wall second-moment closure model provides an improved heat transfer prediction in comparison with the k-e model.
