eddy_visc()

subroutine eddy_visc

(

integer

e

)

Compute eddy viscosity using Vreman model Here is the key difference:

• no wall damping is required
• algebraic, no dynamic procedure

Refer: Vreman, A. W., Physics of Fluids (2004): https://doi.org/10.1063/1.1785131.

\( \alpha_{ij} \) (gradient tensor) @fixme Use Fortran slicing syntax

\( \beta_{ij} = \Delta^2 * \alpha_{mi} \alpha{mj} \) Using BLAS subroutine dgemm See: https://www.netlib.org/lapack/explore-html/d1/d54/group__double__blas__level3_gaeda3cbd99c8fb834a60a6412878226e1.html

Alternatively:

Note \( B_\beta \) is being stored in snrm here

alpha_sq = \( \alpha_{ij} \alpha_{ij} \)

Alternatively alpha_sq = \( trace(\alpha^T \alpha) \)
