Mixing liquids on the micro-scale is difficult because the low Reynolds numbers in microchannels and in microreactors prohibit the use of conventional mixing techniques based on mechanical stirring which induces turbulence. Static mixers can be used to sol ...
Mixing liquids at the micro-scale is difficult because the low Reynolds numbers in microchannels and in microreactors prohibit the use of conventional mixing techniques based on mechanical actuators and induce turbulence. Static mixers can be used to solve ...
We report on powder blasting as a promising technology for the three-dimensional structuring of brittle materials. We investigate the basic parameters of this process, which is based on the erosion of a masked substrate by a high-velocity eroding powder be ...
Cavitation erosion of Francis turbines continues to impose costly repairs and loss of revenues. This erosion is primarily caused by leading edge cavitation. A revue of the literature reveals the non-existence of an absolutely validated detection technique ...
Among the different negative cavitation effects that are associated with the cavitation presence (efficiency drop, noise and vibrations etc.), cavitation erosion is still one of the main limiting features in the modern trend towards designing hydraulic mac ...
Separated flow models are of great interest to model two-phase flow such as Stratified, Stratified-Wavy and Annular flow patterns. Taitel and Dukler proposed a model for Stratified flow assuming that the interfacial effects can be neglected and modelled th ...
Through the new method for automatic extraction of a tidal network from topographic or bathymetric fields described in a companion paper [Fagherazzi et al., this issue], we analyze the morphology of aggregated patterns that we observe in nature in differen ...
The electrochemical cavitation detection technique has been used to locate and measure the instantaneous cavitation erosion rate on a 2D NACA profile tested in the IMHEF high-speed cavitation tunnel. Nineteen titanium probes, flush mounted along the profil ...
The principle of reparametrization invariance is used to derive a dynamical equation for the erosion of the landscape of the drainage basin of river networks. The stationary solutions of the equation are found to have scaling behavior that is consistent wi ...
We analyze the elongation (the scaling properties of drainage area with mainstream length) in optimal channel networks (OCNs) obtained through different algorithms searching for the minimum of a functional computing the total energy dissipation of the drai ...
