Simulation of the Slip Velocity Effect in an AC Electrothermal Micropump [PDF]
Micromachines, 2020 The principal aim of this study was to analyze the effect of slip velocity at the microchannel wall on an alternating current electrothermal (ACET) flow micropump fitted with several pairs of electrodes. Using the finite element method (FEM), the coupled

A novel slip-velocity model to simulate the filtration performance of nanofiber media. [PDF]
Process Saf Environ Prot, 2023 Aerosols such as PM2.5 and PM10 can have an immense impact on human health. With the outbreak of SARS-CoV-2, it is urgent to filter aerosols by media filtration technology.

MHD dissipative Powell-Eyring fluid flow due to a stretching sheet with convective boundary conditions and slip velocity. [PDF]
Sci Rep, 2023 The novelty and motivation of this research can be emphasized by examining how the heat transfer mechanism of a non-Newtonian Powell-Eyring fluid, which flows because of a stretched sheet, is affected by factors like viscous dissipation, the slip ...

Slip velocity of large neutrally buoyant particles in turbulent flows
New Journal of Physics, 2012 We discuss possible definitions for a stochastic slip velocity that describes the relative motion between large particles and a turbulent flow. This definition is necessary because the slip velocity used in the standard drag model fails when particle ...

Velocity Slip in a Deep-sea Slurry Pump and Its Effect on Particle Transportation [PDF]
Journal of Applied Fluid Mechanics, 2023 The slurry pump, which forms the core equipment of the deep-sea mining (DSM) system, provides lifting power for the ore from the seabed to the sea level, which is crucial for the safety of coarse ore particle transportation.

Fully Proprioceptive Slip-Velocity-Aware State Estimation for Mobile Robots via Invariant Kalman Filtering and Disturbance Observer [PDF]
IEEE/RJS International Conference on Intelligent RObots and Systems, 2022 This paper develops a novel slip estimator using the invariant observer design theory and Disturbance Observer (DOB). The proposed state estimator for mobile robots is fully proprioceptive and combines data from an inertial measurement unit and body ...

Flow behaviour and structure of heterogeneous particles-water mixture in horizontal and inclined pipes [PDF]
EPJ Web of Conferences, 2018 The effect of slurry velocity and mean concentration of heterogeneous particle-water mixture on flow behaviour and structure in the turbulent regime was studied in horizontal and inclined pipe sections of inner diameter D = 100 mm.
