We present our finite element modeling and discuss the main principles of our water actuation technique for water transport in micron scale tubes. The effect of water flow actuation by application of surface acoustic waves on the flow rate of water through a tube with the diameter of 0.1 mm. When the tube walls were exposed to an acoustic energy of 27 kHz in experiment, there was a substantial increase in the rate of water flow. A finite element COMSOL Multiphysics Software has been used for this simulation. As input data in our model, we can specify a frequency of the wave, sound speed, the radius of the tube and the density of liquid. The flow rate and the mean flow velocities in the inlet and outlet openings were evaluated in the calculations.
