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.

Surface velocity distribution and rheological proprties estimation of debris flows [PDF]
Italian Journal of Engineering Geology and Environment, 2017 Debris flows are among the most dangerous natural hazards in mountainous areas. In European Alps, they are associated to summer heavy rainfalls and can be extremely destructive. Nevertheless, their rheology, at field scale, is still not well known. These mixtures of debris, water and air behave as non- Newtonian fluids, with a plastic yield strength, a

The Impact of Surface Discontinuities on MEMS Thermal Wind Sensor Accuracy
Sensors, 2023 A 2D calorimetric flow transducer is used to study distortions of the flow velocity field induced by small surface discontinuities around the chip. The transducer is incorporated into a matching recess of a PCB enabling wire-bonded interconnections to ...

A flow velocity dependence of dynamic surface tension in Plateau borders of foam [PDF]
Journal of Colloid and Interface Science, 2020 Liquid drainage through foams is a multiscale process, that primarily occurs through channels known as Plateau borders (PBs). Recent experimental studies of isolated PBs have observed variations in channel surface tension, γ, with liquid flow rate, Q, for systems containing soluble low molecular weight surfactant (LMWS). The current study proposes that
