When miniaturizing fluidic circuitry, the solid walls of the fluid channels become increasingly important1 because they limit the flow rates achievable for a given pressure drop, and they are prone to fouling2. Approaches for reducing the wall interactio
This creates self-healing, non-clogging, anti-fouling and near-frictionless liquid-in-liquid fluidic channels. Manipulation of the field provides flow control, such as valving, splitting, merging and pumping. The latter is achieved by moving permanent magnets that have no physical contact with the...

The spaces between the opposite supports, covered by films of donor and acceptor liquids, respectively, are filled with the membrane phase, flowing countercurrent to the other two. By independent control of the flow rates of the feed and acceptor phases, a significant solute accumulation in the ...
While the bulk flow is moving horizontally, the oil drops will rise due to buoyancy and flow perpendicular to the main flow and collect above the water phase. The water is withdrawn from the bottom and the oil phase from the middle. Level control is maintained through use of a float ...
All the aforementioned techniques have been presented here in the context of multiphase flow measurements; nevertheless, similar issues apply to internal single-phase (liquid) flows, both internal and external when walls are present, since optical distortions can occur at the solid–liquid interfaces ...
This engine was the first Russian rocket engine without a gas generator, equipped with extendable nozzle and without a cooling system; it was capable of multiple firings and thrust control in two planes. The first firing of RD-0146D took place successfully on November 20, 2013 [53]. India ...
Mass transfer coefficients along the different hydrodynamic regions around the bubble ‐ nose, liquid film and wake – were characterized and their values compared with those from literature. The results suggest a promising potential of bubble train flow to enhance organic matter removal from walls in...
Results obtained indicate that the best yield of 71.54% was achieved when the reaction was performed at a temperature of 290 °C, with the rate of flow of the methanol (used both as a reactant and a carrier) kept at a constant of 2 ml/min as the oil mass was kept at an ...
