The variational multiscale method provides a methodical framework for large eddy simulation of turbulent ows. In this work, a particular implementation in the form of a three-level ΓΏnite element method separating large resolved, small resolved, and unresolved scales is proposed. Residual-free bubble

## Abstract In the present paper, a comparative study of numerical solutions for Newtonian fluids based on the latticeβBoltzmann method (LBM) and the classical finite volume method (FVM) is presented for the laminar flow through a 4:1 planar contraction at a Reynolds number of value one, __Re__=1.
In this paper a numerical procedure for simulating two-uid ows is presented. This procedure is based on the Volume of Fluid (VOF) method proposed by Hirt and Nichols 1 and the Continuum Surface Force (CSF) model developed by Brackbill et al. 2 In the VOF method uids of di erent properties are identi
