# Stabilization of convection-dominated flow and turbulence modeling

Are stabilization techniques for convection-dominated flows like SUPG+PSPG, interior penalty methods, etc. able to handle turbulent flows without tubulence model being employed, at least up to some Reynolds numbers? Conversely is stabilization needed for turbulent flow being resolved by some RANS model when Reynolds number becomes larger and problem stiffer?

Generally, what is the relationship between stabilization techniques and RANS models? Are they different approaches to similiar problem?

The common point I see is that turbulence occurs at high Reynolds numbers, where also the factor space discretization times velocity magnitude $hv$ tends to be large, i.e. where upwind stabilization, as it is mimicked in SUPG, is necessary.
