turbulent_wall_powerLaw_incomp Subroutine

public subroutine turbulent_wall_powerLaw_incomp(me, state, bcBuffer, globBC, levelDesc, tree, nSize, iLevel, sim_time, neigh, layout, fieldProp, varPos, nScalars, varSys, derVarPos, physics, iField, mixture)

Power-law wall function for turbulent flow. Calculate velocity and along with that the corresponding PFD at the wall using a wall function based on the power-law. The implementation is based on the following paper: Haussmann, M. et al. (2019) ‘Large-eddy simulation coupled with wall models for turbulent channel flows at high Reynolds numbers with a lattice Boltzmann method — Application to Coriolis mass flowmeter’, Computers & Mathematics with Applications. Elsevier Ltd, 78(10), pp. 3285–3302. The main formulas used from it are mentioned in the code below.

The model constants are chosen according to Werner and Wengle: Wengle, H. and Werner, H. (1993) ‘Large-eddy Simulation of Turbulent Flow Over Sharp-edged Obstacles in a Plate Channel’, (1985), pp. 192–199.

Note, that we use information of the second fluid element FF, to specify quantities at the first fluid element F which is adjacent to the wall W.

Usage


```lua boundary_condition = { { label = 'wall', kind = 'turbulent_wall_powerlaw' } }

This subroutine's interface must match the abstract interface definition boundaryRoutine in bc/mus_bc_header_module.f90 in order to be callable via fnct function pointer.
