Numerical simulation of reacting plane mixing layer by particle method

This paper proposes a two-dimensional particle method for a plane mixing layer with a single-step and irreversible chemical reaction. The vorticity and concentration fields are discretized into the vortex and concentration elements, respectively, and the behavior of the elements is calculated with the Lagrangian method. The reaction is estimated through the calculation for the time rate of change in the strength for concentration element. The method is applied to simulate the reactive plane mixing layer. The simulation demonstrates that the mixing and reaction phenomena caused by the large-scale eddies are successfully captured. It is also confirmed that the effects of the Damköhler number and stoichiometric ratio on the reaction are favorably analyzed by the method.
