A Bochev-Dohrmann-Gunzburger stabilization method for the primitive equations of the ocean
(2013-12-31)We introduce a low-order stabilized discretization of the primitive equations of the ocean with highly reduced computational complexity. We prove stability through a specific inf-sup condition, and weak convergence to a ... -
High-order mixed weighted compact and non-compact scheme for shock and small length scale interaction
(2013-12-31)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 large-eddy simulations of turbulent flows
(2013-12-31)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
(2014-12-31)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
(2014-12-31)This paper deals with the simulation of steady flows in tur- bomachinery. Two approaches are proposed, the first one is the classical multiple-rotating frame method (MRF) by multi- zone approach where the different zones ... -
Unstructured, curved elements for the two-dimensional high order discontinuous control-volume/finite-element method
(2014-12-31)Quadrilateral and triangular elements with curved edges are developed in the framework of spectral, discontinuous, hybrid control-volume/finite-element method for elliptic problems. In order to accommodate hybrid meshes, ... -
Aerodynamic study of a tricycle wheel subsystem for drag reduction
