Sentence examples for rough flow from inspiring English sources

An attempt was made to find a new roughness length scale which provides a good correlation to represent the roughness functions for both transitionally and fully rough flow regimes.

Four situations with/without roughness change in the flow direction, i.e. a smooth hill in smooth flow, a rough hill in rough flow, a smooth hill in rough flow and a rough hill in smooth flow, were considered.

This study investigates zero-pressure-gradient turbulent boundary layers for several rough surfaces in the transitionally rough and fully rough flow regimes.

The surface elevation data were then used in a finite difference time domain (FDTD) model to predict the directivity pattern of the airborne sound pressure scattered by the dynamically rough flow surface.

We analyze four different bed friction parameterizations and we show that the performance of formulations which consider the transition between laminar, smooth turbulent and rough turbulent flow do not improve the results obtained with Manning or Keulegan formulas for rough turbulent flow.

Transition to fully developed rough pipe flow was detected in the enhanced tubes after a critical Reynolds number and the corresponding Prandtl number exponent was estimated to be 0.47.
