Parameter Estimation for Nonideal Reactor Models
Application ID: 12183
Real reactors can be modeled as combinations of ideal reactors. In this example the so-called "Dead zone model" is utilized.
Two ideal CSTRs with interchange are set up to model the real reactor. One CSTR represents the highly agitated region and the other the less agitated region. For this, two parameters relating the volume and exchange rate of the two regions need to be found by comparing the model results to experimental tracer data. Using the Parameter Estimation feature in the Reaction Engineering interface makes this an easy task.
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 Chemical Reaction Engineering Module, or Electric Discharge 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.
