Kiva

KIVA, a transient, three-dimensional, multiphase, multicomponent
code for the analysis of chemically reacting flows with sprays has been
under development at the Los Alamos National Laboratory for the past several
years. The code uses an Arbitrary Lagrangian Eulerian (ALE) methodology
on a staggered grid, and discretizes space using the finite-volume technique.
The code uses an implicit time-advancement with the exception of the advective
terms that are cast in an explicit but second-order monotonicity-preserving
manner. Also, the convection calculations can be subcycled in the desired
regions to avoid restricting the time step due to Courant conditions.
The range of validity of the code extends from low speeds to supersonic
flows for both laminar and turbulent regimes. Arbitrary numbers of species
and chemical reactions are allowed. A stochastic particle method is used
to calculate evaporating liquid sprays, including the effects of droplet
collisions and aerodynamic breakups. Although specifically designed for
performing internal combustion engine calculations, the modularity of
the code allows it for easy modifications for solving a variety of hydrodynamics
problems involving chemical reactions. The code has found a widespread
application in the automotive industry.
Samples of KIVA
Availability of KIVA
The KIVA code is available (for a fee) from Energy Science and Technology
Software Center (ESTSC) at (865) 576-2606. The mailing address for ESTSC
is P.O. Box 1020, Oak Ridge, TN 37831-1020. The email address for ESTSC
is estsc@osti.gov. Distribution
of KIVA code from Los Alamos National Laboratory is only to our collaborators.
For established users, there is now a KIVA mailing list. Questions concerning
difficulties with KIVA and area of applications should first be addressed
to this list.
