An efficient eigenvalue bounding method: CFL condition revisited
F. Xavier Trias, Xavier Álvarez-Farré, Àdel Alsalti-Baldellou +2
Direct and large-eddy simulations of turbulence are often solved using explicit temporal schemes. However, this imposes very small time-steps because the eigenvalues of the (linear…
A rational length scale for large-eddy simulation of turbulence on anisotropic grids
F. Xavier Trias, Jesús Ruano, Alexey Duben +1
Due to the prohibitive cost of resolving all relevant scales, direct numerical simulations of turbulence remain unfeasible for most real-world applications. Consequently, dynamical…
On the Reynolds-number scaling of Poisson solver complexity
F. Xavier Trias, Àdel Alsalti-Baldellou, Assensi Oliva
We aim to answer the following question: is the complexity of numerically solving the Poisson equation increasing or decreasing for very large simulations of incompressible flows?…
Minimum-dissipation model and symmetry-preserving discretization for scalar transport in a turbulent flow
Jing Sun, F. Xavier Trias, Roel Verstappen
This work extends the minimum-dissipation model of large-eddy simulation and symmetry-preserving discretization to account for active or passive scalar transport and complex physic…
Quantifying the checkerboard problem to reduce numerical dissipation
Johannes Arend Hopman, Daniel Santos, Àdel Alsalti-Baldellou +2
This work provides a comprehensive exploration of various methods in solving incompressible flows using a projection method, and their relation to the occurrence and management of…
Energy-consistent discretization of viscous dissipation with application to natural convection flow
Benjamin Sanderse, Francesc Xavier Trias
A new energy-consistent discretization of the viscous dissipation function in incompressible flows is proposed. It is implied by choosing a discretization of the diffusive terms an…
