WebStagnation-point flow under free-stream turbulence 3 kinetic energy and heat transfer – this is termed the ‘stagnation-point anomaly’ (Champion & Libby 1991, 1994; Durbin 1996). A fundamental difficulty with the two-equation models is that turbulence is assumed to be predominantely isotropic and in quasi-equilibrium. 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.
