• Conventional suction pumps incorporate many moving components making construction complex.
• The standing wave pumps use a mechanical valve during the pumping operation at large pressure amplitudes, but a portion of the energy is consumed to overcome friction forces between the moving components and also the inertia of the components.
• Therefore, the solution provided by the present patent overcomes the above-mentioned issues with an improvised solution.

An apparatus for the suction process by converting to a nonuniform valve-less standing wave suction pump comprises:

1. A non-uniform resonator connected to a linear actuator for producing high amplitude standing wave;
2. No moving part rectifiers, used to generate flow which will be pumped or sucked;
3. Rectifying elements for inflow/outflow are located at the pressure antinodes parallel to the direction of acoustic particle displacement displaced reaction.

• The suction and pumping effect is achieved by a set of inflow and outflow fluidic diodes.
• Rectification is achieved without using any moving components in the apparatus construction.
• The inflow diodes are placed at the location of the pressure antinode for the suction process.
• The outflow diodes are placed at the location of the pressure antinode for the pumping effect.
• Further, the rectifying elements include single or multiple numbers of diffuser-nozzle elements working as converging and diverging passages of appropriate area variation respectively.
• The schematic diagram of a non-uniform valve-less standing wave suction pump is shown in Figure 1(A) and (B) (front view and side view of the claimed apparatus)
