Resumen:
We present the adaptation to non-free boundary condictions of a pseudoespectral method based on the (complex) Fourier transform. The method is applied to the numerical integration of the Oberbeck-Boussinesq equations in a Rayleigh-Bénard cell with no-slip boundary conditions for velocity and Dirichlet boundary conditions for temperature. We show the first results of a 2D numerical simulation of dry air convection at high Rayleigh number (Ra~109 ). This results are the base for the later study, bythe same method, of wet convection in a solar still.
