Numerical comparison of nonlinear subgridscale models via adaptive mesh refinement

چکیده
In this paper, we provide a method of evaluating the efficacy of nonlinear subgridscale models for use in the large eddy simulation of incompressible viscous flow problems. We compare subgridscale “artificial” viscosity models using a posteriori error estimation and adaptive mesh refinement. Specifically, we compare α-Laplacian based subgridscale models and discuss the benefits and limitations of different values of α for some standard benchmark problems for the Navier–Stokes equations. c © 2007 Elsevier Ltd.

Inexact Restoration and Adaptive Mesh Refinement for Constrained Optimal Control
A new adaptive mesh refinement algorithm is proposed for solving Euler discretization of stateand control-constrained optimal control problems. Our approach is designed to reduce the computational effort by applying the inexact restoration (IR) method, a numerical method for nonlinear programming problems, in an innovative way. The initial iterations of our algorithm start with a coarse mesh, w...

متن کاملAdaptive moving mesh computations for reaction-diffusion systems
In this paper we describe an adaptive moving mesh technique and its application to reaction-diffusion models from chemistry. The method is based on a coordinate transformation between physical and computational coordinates. The transformation can be viewed as a solution of adaptive mesh partial differential equations (PDEs) which is derived from the minimization of a mesh-energy integral. For a...
متن کاملTowards Simulations of 3d Black Hole Coalescence
I review recent developments in numerical relativity, focussing on progress made in 3D black hole evolution. Progress in development of black hole initial data, apparent horizon boundary conditions, adaptive mesh refinement, and characteristic evolution is highlighted, as well as full 3D simulations of colliding and distorted black holes. For true 3D distorted holes, with Cauchy evolution techn...
متن کاملProtoplanetary disk fragmentation with varying radiative physics , initial conditions and numerical techniques
We review recent results of SPH simulations of gravitational instability in gaseous protoplanetary disks, emphasizing the role of thermodynamics in both isolated and binary systems. Contradictory results appeared in the literature regarding disk fragmentation at tens of AU from the central star are likely due to the different treatment of radiation physics as well as reflecting different initia...
