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.
