On regularity for the Boussinesq system in a bounded domain.

In this paper, we prove the following regularity criterion ω : = curl u ∈ L 1 ( 1 , T ; B M O ) for the 3D Boussinesq system with zero heat conductivity in a bounded domain. Here ω is the vorticity of the fluid velocity field u and BMO denotes the function space of bounded mean oscillation. [ABSTRACT FROM AUTHOR]
