https://doi.org/10.1007/978-1-349-06731-2 in the context of the skew-symmetric formulation of the convective term. Moreover, we introduce a parameter which gives the possibility to downsize possible inflow even more and to enhance the stability further. Numerical examples illustrate the effectiveness of the approach.

J. L. Heaton MA(Cantab) FInstPetub-grid eddy viscosity term. We prove stability and convergence for solutions that only need to bear the natural minimal regularity, in unsteady regime. We also study the asymptotic energy balance of the system. We finally include some numerical tests to assess the performance of the model described in this work.

Outflow Conditions for the Navier-Stokes Equations with Skew-Symmetric Formulation of the Convectiv in the context of the skew-symmetric formulation of the convective term. Moreover, we introduce a parameter which gives the possibility to downsize possible inflow even more and to enhance the stability further.

Investigation of Numerical Wall Functions Based on the 1D Boundary-Layer Equations for Flows with Slat plate, over a backward facing step, and over a smoothly contoured ramp. The improvement of the results compared to universal wall functions become significant in case of separation and reattachment.

Understanding the Limits of Inf-Sup Stable Galerkin-FEM for Incompressible Flows,y discretized problem with reasonable growth of the Gronwall constant for large Reynolds numbers are given together with a critical discussion of the choice of stabilization parameters. The fast solution of the fully discretized problems (using BDF(2) in time) is accomplished via unconditionally stable velocity-pressure segregation.

Cholesky Factorisation of Linear Systems Coming from Finite Difference Approximations of Singularly2013), these solvers may exhibit poor performance for singularly perturbed problems. We provide an analysis of the distribution of entries in the factors based on their magnitude that explains this phenomenon, and give bounds on the ranges of the perturbation and discretization parameters where poor performance is to be expected.

A Multiscale Sparse Grid Technique for a Two-Dimensional Convection-Diffusion Problem with Exponentted to the combination technique outlined by Pflaum and Zhou . We show that this method retains the same level of accuracy, in the energy norm, as both the standard Galerkin and two-scale methods. The computational cost associated with the method, however, is ., compared to . and . for the Galerkin and two-scale methods respectively.
