Traveling-Wave Pump

Fig. 30 Axisymmetric version of a mnlti-stage traveling-wave pump based in the ideas from Figs. 28 and 29...

Valve-Less Rectification Pumps, Figure 20 The principle of the traveling-wave pump, two-phase, three-stage rectifier based on the principle from Fig. 19. A substantial proportion of the pumped liquid does not enter the displacement cavities - instead, it is dragged along with the wave... 

This type of traveling wave tube with cold cathode has been developed and met reasonable performance. However, a good system pumping around the cathode was difficult to achieve in the small enclosed spaces. 

Fig. 1. The traveling-wave micropump assembly. The electrode array chip, with a channel cut in a glass cover mounted on it, is sandwiched between a ceramic carrier and a Plexiglass cover. The volume between the chip and Plexiglass cover forms the circulatory space, consisting of the pump channel itself as well as the two side-channels around the outside of the return flow [31]...

In fluidic pumps, the supplied alternating fluid flow is converted into a mostly one-way (and ideally nonreturn) output flow. One possibility to do it is by generating a series of traveling waves in a channel by alternating outflows and suction in a series of nozzles arranged along... 

Valve-Less Rectification Pumps, Fig. 29 The principle of a traveling-wave peristaltic multi-stage pump driven by a two-phase air flow. A considerable proportion...
