Doubts about these analogies, in particular their application to turbulent flow ... in a laminar boundary layer, has been established by comparison with the Blasius boundary layer equation ...

We conduct numerical simulations (DNS) to study roll waves’ temporal and spatial development on a laminar sheet flow with negligible surface tension. The DNS results are compared with the two-equation ...

What has happened? The phenomenon is related to the differences between laminar and turbulent boundary layer. The boundary layer and its interaction with the local pressure gradient plays a major role ...
