**UNDER CONSTRUCTION**

The model implemented here is the one described in Thielen et al. (Int Journal of Heat and Mass Transfer, 48, 2005, pp.1583-1598).

The model solves the full set Reynolds stresses , a dissipation equation and an elliptic equation for .

The Reynolds stress equation can be written as:

The main idea of the model is to blend the near wall part with the farfiled one via , which is defined as:

With this parameter, the equation for the velocity-pressure-gradient correlation can be written as:

The "homogeneous" part is taken from the SSG (Speziale et al.)

And the near wall part is derived to satisfy the near wall asymptotic behaviour and stress budgets:

with the following definitions:

The constants used are:
