Surface velocity model of the flow caused by a DBD plasma actuator

open access: yesNihon Kikai Gakkai ronbunshu, 2018
The surface velocity model is proposed for modelling the flow caused by a DBD plasma actuator. While numerical model presented up to now for the DBD plasma actuator, i.e.

Effect of Flow Velocity on the Surface Fouling (Dept.M) [PDF]

open access: yesMEJ. 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.

Surface velocity distribution and rheological proprties estimation of debris flows [PDF]

open access: yesItalian 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

A flow velocity dependence of dynamic surface tension in Plateau borders of foam [PDF]

open access: yesJournal 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

Velocity profiles of fluid flow close to a hydrophobic surface [PDF]

open access: yesEPJ 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 ...

The Impact of Surface Discontinuities on MEMS Thermal Wind Sensor Accuracy

open access: yesSensors, 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 ...
