Micropumps are key components of microfluidic systems with applications ranging from biological fluid handling to microelectronic cooling.
This model simulates the mechanism of a valveless micropump, that is designed to be effective at low Reynolds numbers, overcoming hydrodynamic reversibility. Valveless pumps are often preferred in microfludic systems because they minimize the risk of clogging and are gentle on biological material.
The Fluid-Structure Interaction interface is used to solve for the flow of the fluid and the associated deformation of the structure. In addition, the Global ODEs and DAEs interface is used to demonstrate how to perform a time resolved integration of the total flow throughout the pumping cycle.
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® and
- either the MEMS Module, Multibody Dynamics Module, or Structural Mechanics Module
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 Specification Chart 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.
