Lattice Boltzmann method for the production and evolution of spiral waves
用晶格玻尔兹曼方法研究螺旋波的产生机制和演化行为

We proposed a five-speed lattice Boltzmann method to investigate the evolution of the reaction-diffusion system. As an example, the production mechanism and evolution of the spiral wave were studied. We found that the system may evolve to three final states: homogenous, chaotic, and spiral waves-like, depending on the parameter of the system, and the crushing of the spiral waves in Selkov reaction-diffusion system belongs to the Doppler class.
