Boundary layer development from transition provoking devices
… turbulent re-attachment, and transition due to isolated spherical roughness elements.<br/><br/>The concept of statistical similarity in transition regions has been confirmed for the cases of free transition and for transition due to a two-dimensional trip wire, with the streamwise mean …

Effects of Various Shaped Roughness Elements in Two-Dimensional High Reynolds Number Turbulent Boundary Layers
Modeling the effects of surface roughness is an area of concern in many practical engineering applications. Many current roughness models to this point have involved the use of empirical 'constants' and equivalent sand grain roughness. These underdeveloped concepts have little direct relationship …
