The nature of an oscillatory (turbulent) boundary layer over a rough wall was studied experimentally by oscillating a flat plate in an otherwise quiescent fluid. The velocity field was measured with respect to a fixed (laboratory) coordinate system and was converted to that relative to a ...
Existing and newly acquired data from zero pressure gradient rough-wall turbulent boundary layers are used to clarify the leading order balances of terms in the mean dynamical equation. For the variety of roughnesses examined, it is revealed that the mean viscous force retains dominant order above...

wall turbulence. Because of space limitations we restrict ourselves to the fluid dynamics of fully turbulent flows over rough walls, neglecting other important topics. One of them is transition, which can be promoted (Schlichting 1968, pp. ...
laminar to turbulent transitions/ empirical predictorfriction factorsflow reversalExploratory measurements of oscillatory boundary layers were conducted over a smooth and two different rough beds spanning the laminar, transitional and turbulent flow regimes using a multi-camera 2D-PIV system in a small ...
Measurements for heat transfer in the rough wall turbulent boundary layers are presented. This paper summarizes the previous experimental results for six test surfaces five rough and one smooth. Three of the rough surfaces are smooth plates roughened with hemispherical elements uniformly distributed 2, ...
Sediment saltation in a rough-wall turbulent boundary layer was simulated with a coupled model with large eddy simulation and a discrete element model. The aim is to quantify the saltation process using eddy-resolving fluid simulations and Lagrangian particle tracking. The four-way coupling approach ...
