A parallel algorithm for the detailed numerical simulation of reactive flows

摘要

The aim of this work is to use parallel computers to advance in the simulation of laminar flames using finite rate kinetics. To this end, a parallel version of an existing sequential, subdomain-based CFD code for reactive flows has been developed. In this paper, the physical model is described. The advantages and disadvantages of different strategies to parallelize the code are discussed. A domain decomposition approach with communications only after outer iterations is implemented. It is shown, for our specific problem, that this approach provides good numerical efficiencies on different computing platforms, including clusters of PC. Illustrative results are presented.
