19 k-epsilon Eddy viscosity from single length scale Turbulent diffusion occurs only at specified scale RNG k-epsilon Account for different scales of motion k-omega Viscous sub-layer flows Adverse pressure gradients and separating flows

20 Shear Stress Transport (SST) k-ω near boundary k-ε in free-stream Adverse pressure gradients & separating flows Reynolds Stress Model (RSM) Reynolds Stresses directly computed Directional effects of Reynolds stress fields More suitable for anisotropic turbulence
