- FENE-P
FENE-P is a continuous model of
polymer . The nameFENE stands for finitely extensible nonlinear elastic while P stands for the closure proposed by Peterlin. It takes the dumbbell version of theFENE model and assumed the Peterline statistical closure for the restoring force.Advantages
FENE-P is one of few polymer models that can be used in fluid dynamics simulations (
CFD ) since it removes the need of statistical averaging at each grid point at any instant in time. It is demonstrated to be able to capture some of the most important polymeric flow behaviors such aspolymer turbulence drag reduction andshear thinning . It is the most commonly used polymer model that can be used in aturbulence simulation since turbulence DNS is already extremely expensive.Disadvantages
Due to its simplifications, FENE-P is not able to show the
hysteresis effects that polymers have, which to the contrast the FENE model is capable of.References
