Accounting for wall roughness effects in turbulence models : a wall function approach
2017
To meet expectations of simulation tools for ice accretion, requiring low CPU consuming flow solvers, a wall function has been developed to complement a RANS turbulent model involving roughness corrections. The latter belongs to the classical family of equivalent sand grain models. The proposed wall model relies on the Suga et al. wall function approach. Among the improvements brought by the new model, the wetted surface is now considered as a parameter that controls the heat transfer on rough
