In ultrasonic pumps, liquid is sucked into a pipe whose end is faced at an ultrasonic vibrating surface with a small gap. To simulate the pump operation, a model of the ultrasonic pump based on the squeeze film theory is presented in this paper. Nonlinear compressibility is introduced to the liquid in the gap, and the static pressure is calculated as a time average over the period of the ultrasonic vibration of the gap. We investigate the applicability of the model by comparing the simulated static pressure with the experimental pump pressure. The simulated static pressures as a function of the gap and the vibration displacement amplitude approximately agree with the experimental pump pressures if the squeeze film factor is suitably chosen.
