dc.description.abstract | In this work we present a Reduced Basis VMS-Smagorinsky Boussinesq
model, applied to natural convection problems in a variable height cavity,
in which the buoyancy forces are involved. We take into account in this
problem both physical and geometrical parametrizations, considering the
Rayleigh number as a parameter, so as the height of the cavity. We
perform an Empirical Interpolation Method to approximate the sub-grid
eddy viscosity term that let us obtain an a ne decomposition with respect
to the parameters. We construct an a posteriori error estimator, based
upon the Brezzi-Rappaz-Raviart theory, used in the greedy algorithm for
the selection of the basis functions. Finally we present several numerical
tests for di erent parameter con guration. | es |
