Angioplasty

Adaptive Direct Numerical Simulation with Spatially-Anisotropic Wavelet-Based Refinementctures and unresolved flow motions is achieved through the application of a wavelet thresholding filter. For very small threshold values, the effect of residual motions upon the resolved flow dynamics can be completely neglected, which leads to the adaptive Wavelet-based Direct Numerical Simulation (W-DNS) approach.

无关紧要

Efficient Pressure-Correction Method for Interfacial Tracking Appropriate for the Immersed Boundary n challenges, is the reduction of the computational cost which is still significantly higher when compared to single-fluid problems. This is mainly due to the variable coefficients Poisson equation arising from the projection method to impose mass conservation.

Devastate

On the Eddy Viscosity Associated with the Subgrid Stresses the unresolved scales in the equations of motion for the Large Eddy Simulation (LES) approach. Indeed, the subgrid scale (sgs) viscosity approach allows from an energetic point of view to respect the dissipative nature of turbulence.

Towards Adaptive Mesh Refinement for the Spectral Element Solver Nek5000roblems. Some work has been made recently to provide Nek5000 with adaptive mesh refinement (AMR) capabilities in order to facilitate the generation of the grid and push forward the limit in terms of problem size and complexity [.].
