A BochevDohrmannGunzburger stabilization method for the primitive equations of the ocean
(20131231)We introduce a loworder stabilized discretization of the primitive equations of the ocean with highly reduced computational complexity. We prove stability through a specific infsup condition, and weak convergence to a ... 
Highorder mixed weighted compact and noncompact scheme for shock and small length scale interaction
(20131231)It is critical for a numerical scheme to obtain numerical results as accurate as possible with limited computational resources. Turbulent processes are very sensitive to numerical dissipation, which may dissipate the small ... 
A variational finite element model for largeeddy simulations of turbulent flows
(20131231)The authors introduce a new Large Eddy Simulation model in a channel, based on the projection on finite element spaces as filtering operation in its variational form, for a given triangulation {T h}h>0. The eddy viscosity ... 
Identification of defects originated during the filling of cast pieces through particles modelling
(20141231)In casting processes, strong recirculation zones may trap air, gases and strip particles of sand off the mold affecting seriously the quality of the cast pieces. Especially during the filling of molten pieces with large ... 
Efficient Rotating Frame Simulation in Turbomachinery
(20141231)This paper deals with the simulation of steady flows in tur bomachinery. Two approaches are proposed, the first one is the classical multiplerotating frame method (MRF) by multi zone approach where the different zones ... 
Unstructured, curved elements for the twodimensional high order discontinuous controlvolume/finiteelement method
(20141231)Quadrilateral and triangular elements with curved edges are developed in the framework of spectral, discontinuous, hybrid controlvolume/finiteelement method for elliptic problems. In order to accommodate hybrid meshes, ...
