| Outline of Final Research Achievements |
In order to realize the combustion analysis using detailed chemical kinetic models, the development and implementation of the high speed method was carried out. In addition, I compared the experimental values using developed code.
First, I developed the explicit and implicit methods for solving the chemical reaction equation, which have main computational cost in the combustion simulation. These methods achieve speedup several hundred times while maintaining the same precision as the conventional method. I also succeeded in drastically reducing the number of grid points by implementing the Artificial Thickened Flame method and the Adaptive Mesh Refinement method to further reduce the computational cost.
By using the code developed in this research, the calculations are carried out on the two-dimensional laboratory scale, and it was able to to obtain the results that are in good agreement with the experiment.
