  title={Improvement in Computational Efficiency for HCCI Engine Modeling by Using Reduced Mechanisms and Parallel Computing},
  author={Amr Ali and G. Cazzoli and S. Kong and R. Reitz and C. Montgomery},
Detailed chemistry was used with engine CFD code for HCCI engine combustion modeling in order to achieve a more accurate analysis. The present study improved the computational efficiency by using reduced mechanisms and parallel computing schemes. In the reduced mechanism, the number of species and reactions were reduced using a systematic approach by the introduction of quasi-steady-state assumptions. Results of using the reduced mechanism in the engine study agreed reasonably well with those… Expand
