Summary:

In situ adaptive tabulation (ISAT) has been implemented into HCCI multidimensional modeling with detailed chemical kinetics, and the performance of ISAT was discussed. The results indicate that ISAT can reduce the computational time remarkably, and the global error can be efficiently controlled. The ISAT without growth and a reversal traverse were tested to ISAT, but they didn't influence the performance of ISAT greatly. Taking account of the character issues of chemical reactions during HCCI combustion process, an enhanced approach, the partial ISAT (PaISAT), was presented, which can significantly improve the accuracy and speed-up factor. The memory occupancy needed by ISAT was reduced based on the dynamic trimming technique
