AbstractA dynamic multi-timescale (MTS) method is introduced to a well-validated computational fluid dynamic (CFD) solver, aiming at development of a fast and efficient method for simulations of reacting with large detailed chemical kinetics. The performance capability of the MTS method are validated for several reaction systems and a wide range of pressure and temperature conditions, showing its accuracy and dramatic reduction of computational time, relative to a conventional direct integration method (VODE). Shock tube problems are used to examine the performance of the MTS method on the CFD solver, demonstrating its potential of handling reactive flow simulations with large detailed chemical kinetics efficiently.
