Abstract

Multi time scale(MTS)simulation of homogeneous ignition of n-heptane/air is conducted using detailed kinetic mechanism. It is found that the ignition process covers a very broad range of time scales. In order to accurately and efficiently simulate this process, the MTS method is introduced and different time step for numerical integration is adopted for species with different characteristic time. Extensive numerical tests for n-heptane/air ignition under a wide range of initial conditions show that the MTS method can accurately and efficiently simulate the ignition process. The MTS method can be used in direct numerical simulation of reactive flows in order to significantly reduce computation time.
