Piezoelectric Micropump
Application ID: 90031
This tutorial model is kindly provided by Riccardo Vietri, James Ransley and Andrew Spann at Veryst Engineering, LLC. Piezoelectric micropumps are frequently used in medical applications because of their ability to precisely control the metering of very small volumes of fluids or gases. This example shows how to simulate a simple, non-resonant micropump, suitable for low flow rate applications. The model demonstrates the combination of piezoelectric materials with a fluid-structure interaction, and also illustrates the use of a simple velocity-dependent formula to account for the presence of valves on the inlet and outlet boundaries.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® et
- soit le Module Acoustics, Module MEMS, ou Module Structural Mechanics et
- soit le Module MEMS, Module Multibody Dynamics, ou Module Structural Mechanics et
- soit le Module AC/DC, Module MEMS, Module Plasma, ou Module Semiconductor
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Grille des Spécifications and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
