Global existence and exponential decay of strong solutions for the three-dimensional Boussinesq equations

In this paper, we consider the global existence of strong solutions to the three-dimensional Boussinesq equations on the smooth bounded domain Ω . Based on the blow-up criterion and uniform estimates, we prove that the strong solution exists globally in time if the initial L^2 -norm of velocity and temperature are small. Moreover, an exponential decay rate of the strong solution is obtained.
