An accurate Cartesian grid method for viscous incompressible flows with complex immersed boundaries

Journal Article Ye, T; Mittal, R; Udaykumar, H; ... - Journal of Computational Physics

A Cartesian grid method has been developed for simulating two-dimensional unsteady, viscous, incompressible flows with complex immersed boundaries. A finite-volume method based on a second-order accurate central-difference scheme is used in conjunction with a two-step fractional-step procedure. The key aspects that need to be considered in developing such a solver are imposition of boundary conditions on the immersed boundaries and accurate discretization of the governing equation in cells that are cut by these boundaries. A new interpolation procedure is presented which allows systematic development of a spatial discretization scheme that preserves the second-order spatial accuracy of the underlying solver.

Parallel adaptive refinement for unsteady flow calculations on 3D unstructured grids

Journal Article Waltz, Jacob - International Journal for Numerical Methods in Fluids

A parallel adaptive refinement algorithm for three-dimensional unstructured grids is presented. The algorithm is based on an hierarchical h-refinement/derefinement scheme for tetrahedral elements.The algorithm has been fully parallelized for shared-memory platforms via a domain decomposition of the mesh at the algebraic level. The effectiveness of the procedure is demonstrated with applications which involve unsteady compressible fluid flow. A parallel speedup study of the algorithm also is included.

Finite-difference immersed boundary method consistent with wall conditions for incompressible turbulent flow simulations

Journal Article Ikeno, Tsutomu; Kajishima, Takeo - Journal of Computational Physics

An immersed boundary method to achieve the consistency with a desired wall velocity was developed. Existing schemes of immersed boundary methods for incompressible flow violate the wall condition in the discrete equation system during time-advancement. This problem arises from the inconsistency of the pressure with the velocity interpolated to represent the solid wall, which does not coincide with the computational grid. The numerical discrepancy does not become evident in the laminar flow simulation but in the turbulent flow simulation. To eliminate this inconsistency, a modified pressure equation based on the interpolated pressure gradient was derived for the spatial second-order discretemore »« less
