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 ...

Purpose - The purpose of this paper is to assess the Boussinesq approach for a wide range of Ra (10 × 6 to 10 × 11) in two-dimensional (square cavity) and three-dimensional (cubic cavity) problems for air- and liquidfilled ...

We report experimental results on the heat transfer and instability onset of a Rayleigh-Benard convection cell of aspect ratios 6:3:1 filled with a high Prandtl aqueous solution of glycerol under feedback control. We ...

Se presenta la adaptación a condiciones de contorno no libres de un método pseudo-espectral basado en transformada de Fourier compleja. El método se aplica a la integración numérica de las ecuaciones de Oberbeck-Boussinesq ...

The CFD thermal hydraulic simulation of a Pressurized Heavy Water Reactor (PHWR) moderator tank was performed. Heating was achieved by considering two heat sources, conduction/convection through the coolant channels and ...

A two-dimensional (2D) free surface flow model already used to study the Rayleigh instability of thin films lining the interior of capillary tubes under the presence of insoluble surfactants [D. M. Campana, J. Di Paolo, ...
