Shape Optimization of a 3D Tesla Microvalve
Application ID: 75311
Tesla microvalves exploit the non-linear nature of inertial flow to create anisotropic flow resistance. They can be used as robust valves owing to their passive working mechanism, but for many applications the diodicity is too low. Two-dimensional simulations and optimization over-estimate the diodicity, if the channel height is similar to the other dimensions of the device. This model demonstrates 3D shape optimization at a Reynolds number of 200. Import/export of the design is combined with a model method, so inverted elements can be avoided even though the geometry deformations are large.
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
- Optimization Module and
- either the CFD Module, Heat Transfer Module, Microfluidics Module, or Polymer Flow 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.
