Title: A multidomain boundary element method for two equation turbulence models Ramšak, Matjaž (Author)Škerget, Leopold (Author) http://dx.doi.org/10.1016/j.enganabound.2005.07.007 English Unknown () 1.01 - Original Scientific Article FS - Faculty of Mechanical Engineering The paper deals with the multidomain Boundary Element Method (BEM) for modelling 2D complex turbulent flow using low Reynolds two equation turbulence models. While the BEM is widely accepted for laminar flow this is the first case, where this method is applied for complex flow problems using ▫$k-epsilon$▫ turbulence model. The integral boundary domain equations are discretised using mixed boundary elements and a multidomain method also known as subdomain technique. The resulting system matrix is overdetermined, sparse, block banded and solved using fast iterative linear least squares solver. The simulation of turbulent flow over a backward step is in excellent agreement with the finite volume method using the same turbulent model. fluid mechanics, turbulent flow, boundary element method, incompressible viscous fluid, stream function-vorticity formulation, two equation turbulence model, backward facing step flow 2005 532.517.4:519.61/.64 0955-7997 10107670 URN:SI:UM:DK:6TMPCZBW 1154 58 Misc.
