(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. In Computers & Mathematics with Applications 78 (10), pp. 3285–3302. DOI: 10.1016/j.camwa.2019.04.033.

The explicit power-law in terms of friction velocity given in Eq. 33 in S. Wilhelm, J. Jacob, and P. Sagaut, "An explicit power-law-based wall model for lattice Boltzmann method–Reynolds-averaged numerical simulations of the flow around airfoils", Physics of Fluids 30, 065111 (2018) https://doi.org/10.1063/1.5031764

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.
