Skin friction and pressure: the "footprints" of turbulence
2004
Physica D : Non-linear phenomena
This article addresses the information available at the wall in the problem of state estimation in wall-bounded incompressible flows. It is shown that, if precise measurements are made of the two components of wall skin friction, ∂u ∂y and ∂w ∂y, and the wall pressure, p, all terms in the Taylor-series expansions of the flow state near the wall may be determined. Combining this fact with the analyticity of solutions of the Navier-Stokes equation on the attractor, in theory complete
