The Turbulent Flow, Realizable k-ε interface uses the revised two-equation k-ε model with realizability constraints. Flow close to walls is modeled using wall functions.

The Turbulent Flow, k-ω interface uses the Wilcox revised two-equation k-ω model. Flow close to walls is either modeled using wall functions or resolved down to the wall depending on local mesh resolution. The physics interface includes a wall distance equation.

The Turbulent Flow, SST interface uses the Menter SST k-ω two-equation model. Flow close to walls is either modeled using wall functions or resolved down to the wall depending on local mesh resolution. The physics interface includes a wall distance equation.

|
The Turbulent Flow, Low Re k-ε interface uses the AKN two-equation k-ε model with realizability constraints. The AKN model is a so-called low-Reynolds number model, which means that it resolves the flow all the way down to the wall. The AKN model depends on the distance to the closest wall. The physics interface therefore includes a wall distance equation.

The Turbulent Flow, Spalart-Allmaras interface uses the one-equation
 model that is designed mainly for aerodynamic applications. Flow close to walls is either modeled using wall functions or resolved down to the wall depending on local mesh resolution. The physics interface includes a wall distance equation. |
