Abstract

Numerical simulations of reactive flows are among the most computational demanding applications in the scientific computing world; the relevant codes are often difficult to maintain and improve, and the solution methods employed may not always be the most up-to-date.In this work we focus on an activity carried out in the context of the PINEAPL project, funded by the European Commission. We have developed a parallel version of the KIVA-3 application software by integrating routines from the parallel sparse solvers of the PINEAPL library in the code, an obtained some interesting results in terms of speed, efficiency and robustness.KIVA-3 is a widely used CFD software for numerical simulation of chemically reactive flows, specifically tailored for engine applications. The parallel version of KIVA-3 is currently in use at Piaggio for the simulation of the scavenging process in two-stroke engines. The reduction of the simulation times obtained with the new code produced important effects on the overall simulation procedure of new engines.
