    of these models is also derived The new models result in a consistent numerical method that is relatively simple to implement The need for a dynamic procedure in determining model coefficients is no longer required The new LES models are tested on a decaying Taylor Green vortex generalized to MHD and benchmarked against classical LES turbulence models The LES simulations are run in a periodic box of size π π

    WILEY VCH Verlag Abstract Melts of symmetric three arm stars are generated using a novel iterative method In this method an equilibrated low molecular weight configuration is used to generate progressively higher molecular weights by affine scaling and equilibration At each stage in the progression the synthetically lowered entanglement density allows bypassing of the exponentially large relaxation times of branched polymers The quality of equilibration was assessed by measuring the
