Velocity profiles of fluid flow close to a hydrophobic surface [PDF]
EPJ Web of Conferences, 2017 The results of research on viscous liquid flow upon a superhydrophobic surface are presented in the paper. In the introduction, the degrees of surface hydrophobicity in correlation with an adhesion coefficient are defined. The usage of the adhesion coefficient for the definition of a new boundary condition is employed for expressing the slip of the ...

Change in drag, apparent slip and optimum air layer thickness for laminar flow over an idealised superhydrophobic surface [PDF]
, 2013 Analytic results are derived for the apparent slip length, the change in drag and the optimum air layer thickness of laminar channel and pipe flow over an idealised superhydrophobic surface, i.e. a gas layer of constant thickness retained on a wall.

A semi-analytical solution of surface flow and subsurface flow on aslope land under a uniform rainfall excess [PDF]
, 2014 A new approach is proposed to analyze the surface flow and subsurface flow passing over a pervious ground under a uniform rainfall excess. The flow field is divided into two regions that are called water layer and soil layer.

Handbook for Surface Flow Velocity Measurement
, 2019 Acquisition of real-time hydraulic data is an essential component for flood forecasting. However, we frequently face difficulties in obtaining discharge data using classical contact methods during high magnitude floods and for systems experiencing rapid hydro-geomorphological adjustment.

Flow and Turbulence driven Water Surface Roughness and Gas Exchange Velocity in Streams
E3S Web of Conferences, 2018 Gas exchange velocity in streams and rivers controls fluxes of atmospheric gases across the air-water interface and is commonly related to the turbulence at the water side. Similarly, river flow hydraulics influences the water surface roughness, which is
