SURFACE FLOW VELOCITY MEASUREMENTS FROM UAV-BASED VIDEOS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 Most measuring methods for determining the volumetric flow rate or surface flow velocity have in common that they cannot be safely used under extreme outflow conditions. Especially in catastrophic situations, it is of particular interest to determine the

Conventional Point-Velocity Records and Surface Velocity Observations for Estimating High Flow Discharge [PDF]
Entropy, 2014 Flow velocity measurements using point-velocity meters are normally obtained by sampling one, two or three velocity points per vertical profile. During high floods their use is inhibited due to the difficulty of sampling in lower portions of the flow ...

Journal of Pipeline Science and Engineering, 2021 The critical flow velocity phenomenon is common in erosion-corrosion of many materials. It is of great importance to develop methods to determine the critical flow velocity and understand mechanisms of the phenomenon so that it can be used for proper ...

New boundary conditions for fluid interaction with hydrophobic surface [PDF]
EPJ Web of Conferences, 2018 Solution of both laminar and turbulent flow with consideration of hydrophobic surface is based on the original Navier assumption that the shear stress on the hydrophobic surface is directly proportional to the slipping velocity.

Effect of Flow Velocity on the Surface Fouling (Dept.M) [PDF]
MEJ. Mansoura Engineering Journal, 2020 La vitesse lente est l'un des paramètres les plus importants affectant le taux d'encrassement sur les surfaces de transfert de chaleur. Une étude expérimentale est réalisée pour étudier l'effet de la faible vitesse sur l'encrassement de surface pour le type d'encrassement particulaire.
