KIVA-3: A KIVA program with block-structured mesh for complex geometries
This report describes the KIVA-3 computer program for numerical calculation of transient, two- and three-dimensional chemically reactive fluid flows with sprays. KIVA-3 is an extension of the earlier KIVA-II, uses the same numerical solution procedure, and solves the same set of equations. The full generality of KIVA-II has been retained; thus KIVA-3 is applicable to laminar or turbulent flows, subsonic or supersonic flows, and single-phase or dispersed two-phase flows. KIVA-3 differs from KIVA-11 in that it uses a block-structured mesh with connectivity defined through indirect addressing. The departure from a single rectangular structure in (i,j,k) logical space allows complex geometries to be modeled with significantly greater efficiency than was previously possible because large regions of deactivated cells are no longer necessary. Cell-face boundary conditions permit greater flexibility and simplification in the application of boundary conditions. This report discusses those features of KIVA-3 that differ from KIVA-II, the input required from a mesh generation preprocessor, and the output provided to a graphics postprocessor. Basic pre and post-processors are included in the KIVA-3 package, and are also described.
