Development of turbulent boundary layers past a step change in wall roughness

Article English OPEN
Hanson, R.E.; Ganapathisubramani, B.;

In this study, the development of a boundary layer past a change in surface roughness (from rough to smooth, R -> S) is examined. Measurements of the flow were made by hot wires, whereas the friction velocity was estimated by Preston tube measurements. By means of a ... View more
