This paper deals with a study on the Oberbeck-Boussinesq approximation describing the motion of an incompressible, heat-conducting fluid occupying a flat torus. The main objective is to show that the global-in-time weak solution of the Oberbeck-Boussinesq system has global regularity with some condition only on the speed field, i.e., without imposing any restrictions on the temperature.

摘要

This paper deals with a study on the Oberbeck-Boussinesq approximation describing the motion of an incompressible, heat-conducting fluid occupying a flat torus. The main objective is to show that the global-in-time weak solution of the Oberbeck-Boussinesq system has global regularity with some condition only on the speed field, i.e., without imposing any restrictions on the temperature.
