Abstract:
This article concerns the behavior of the initial layer appearing at large Prandtl number
in Boussinesq equations with the ill initial data. By using the asymptotic
expansion methods of singular perturbation theory, we establish an approximate solution
and the rate of convergence as the Prandtl number tends to infinity.
Our results improve the existing ones concerning thermosolutal convection.
