Title: A Block-Structured KIVA Program for Engines with Vertical or Canted Valves

Abstract

KIVA-4 is the latest version of the series of KIVA codes. While KIVA-4 maintains the full generality of KIVA-3V, it adds the capability of computing with unstructured grids. Unstructured grids can be generated more easily than structured grids for complex geometries. The unstructured grids can be composed of a variety of elements including hexahedra, prisms, pyramids, and tetrahedra. However the numerical accuracy is less when the grid is not composed of hexahedra. KIVA-4 was developed to work with the many geometries accommodated with KIVA-3V which include 2D axisymmetric, 2D planar, 3D axisymmetric sector geometries, and full 3D geometries. KIVA-4 also features a multicomponent fuel evaporation algorithm. Many of the numerical algorithms in KIVA-3V do generalize nicely to unstructured meshes. However fundamental changes were needed in the solution of the pressure equation and the fluxing of momentum. In addition, KIVA-4 loops over cell faces to compute diffusion terms. More details can be found in Torres, D.J. and Trujillo, M.F., KIVA-4: An unstructured ALE code for compressible gas flow with sprays, Journal of Computational Physics, 2006, vol. 219, pp. 943-975. PACKAGE TESTED USING LINUX OPERATING SYSTEM. MAY BE MODIFIED TO RUN USING UNIX OR WINDOWS.
