ESDU 09016 provides a method, based on that of van Driest and
Blumer, which enables the required height of roughness elements in
a boundary-layer transition band to be estimated from the local
boundary-layer displacement or momentum thickness, together with
conditions at the edge of the boundary layer. The item is
accompanied by a GUI-based program which, when used in conjunction
with a coupled integral-boundary-layer aerofoil or wing /body code
(e.g. VGK or VFP), permits rapid evaluation of the
required roughness height over a range of test conditions. The
program also provides the option determine the required roughness
height to fix transition on a simple equivalent flat plate.
