Impact of Surface Roughness on Local Aerodynamics Using a Three-Dimensional Navier-Stokes Solver
2004
42nd AIAA Aerospace Sciences Meeting and Exhibit
unpublished
Accurate simulation of glaze ice accretion requires detailed models which account for the impact of small scale surface roughness on boundary layer development and heat transfer. The current study investigates the feasibility of using a Direct Numerical Simulation (DNS) approach in order to study the flow over roughness and subsequently develop the desired roughness models. First, the limits of the DNS approach are investigated and the method is found to be limited by the value of the roughness
