Web1 de jan. de 2002 · The model is succinctly termed the linear production model (LP model). The anisotropy of the Reynolds tensor is defined by equation (1) and modelled by equation (2) for an eddy-viscosity approach. (1) a i j = u i u j ¯ k − 2 3 δ i j (2) a i j = − v T k 2 S i j. The turbulent energy production term results in (3) for the exact term, and in ...
