Abstract: Two new robust numerical wall functions are evaluated and the effect of different approximations used in earlier numerical wall functions by Craft et al. (2004) and by Bond and Blottner (2011) are demonstrated. A standard… read more here.

Abstract: Abstract An approach to extend the near-wall treatment approach of RANS turbulence models using wall functions for rough surfaces is proposed. The formulation is consistent with the low-Reynolds number turbulence model roughness extension, leading to… read more here.

Abstract: Abstract Large-eddy simulations (LESs) for two different T-junctions are performed for the prediction of thermal mixing loads on piping. In particular, the effects of wall treatment and mesh on temperature and wall heat flux fluctuations… read more here.
