Navier-Stokes Analysis of Two-Dimensional Roughness Pattern Under Turbulent Flow Regime

Fre´de´ric Billy, Mihai¨ Arghir, Ge´rard Pineau
Proc. ASME. TRIB2004, ASME/STLE 2004 International Joint Tribology Conference, Parts A and B, 559-568, October 24–27, 2004

... consists of identical and equally spaced rectangles with characteristic lengths at least one order of magnitude larger than the clearance of the thin film. Periodic boundary conditions enable the analysis of a single groove and the complete Navier-Stokes analysis is carried on for turbulent Reynolds...

A Modified Turbulence Model for Low Reynolds Numbers: Applications to Hydrostatic Seals

Noe¨l Brunetie`re
Proc. ASME. TRIB2004, ASME/STLE 2004 International Joint Tribology Conference, Parts A and B, 503-515, October 24–27, 2004
