Facultad de Matemática, Astronomía y Física; Argentina. We present the adaptation to non–free boundary conditions of a pseudospectral 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 (R ∼ 10^9). These results are the basis for the later study, by the same method, of wet convection in a solar still. publishedVersion Fil: Ramos, Ivana Carola. Universidad Nacional de Córdoba.
