MODEL TUNING AND VALIDATION

The ETAB model has been integrated into KIVA-3, a computer code developed at Los Alamos National Laboratory, U.S.A. This program solves the three-dimensional, transient, Reynolds/Favre-averaged conservation equations for mass, species, momentum and energy, together with the k-epsilon turbulence model and is coupled with a stochastic spray evolution law.
