| Research Abstract |
Reactive flow analysis for complex system such as automobile engine knocking and vibratory combustion in gas turbine needs fluid dynamic simulation coupled with detailed chemical kinetics. Because of very large numbers of chemical species involved in combustion, such reactive flow analysis is extremely difficult. We successfully developed a new method for the reduction of number of chemical species. In addition, an ultra fast solver of chemical kinetic equations is also developed and implemented into compressible CFD (computer fluid dynamics) code. As a result, reactive flow analysis now become possible for automobile engine knocking.
