Reynolds stress transport turbulence model selections include: - Launder, Reece and Rodi (LRR) - Speziale, Sarkar and Gatski (SSG)
Background🔗
The Reynolds stress transport equation reads:
\[\Ddt{\tensor{R}} = \underbrace{\tensor{P}}_{production} + \underbrace{\tensor{\Pi}}_{pressure-strain} - \underbrace{\tensor{\epsilon}}_{dissipation} + \underbrace{\tensor{D}}_{diffusion} + \underbrace{\tensor{\Omega}}_{rotation}\]Here, the production term \(\tensor{P}\) is given by:
\[\tensor{P} = - \tensor{R} \dprod \left(\grad \u + \left(\grad \u \right)^T \right)\]All other terms on the r.h.s. require modelling.
