文摘

We have proposed a moving mesh scheme for the two-step chemical reaction model.

We have proposed positivity-preserving improvements for the moving mesh scheme.

Our scheme can obtain good results with fewer grid cells.

The front step and detonation diffraction problem is successfully simulated.

Mesh is adaptive with the wave front in our simulations.
