A lattice Boltzmann model for the coupled cross-diffusion-fluid system

作者：

Highlights：

• Develop a lattice Boltzmann model for the general cross-diffusion-fluid system.

• Model the cross-diffusion terms through including extra collision operators.

• Recover the governing equations from our model through direct Taylor expansion.

• Study the chemotaxis-fluid and double-diffusion convection systems through our model.
