Thermal Decomposition of Beta-Carotene in a Flow Reactor
Application ID: 105941
This tutorial illustrates how to use the Uncertainty Quantification (UQ) functionality to answer questions regarding sensitivity and reliability of a flow reactor with thermal decomposition. The tutorial investigates what uncertainties in parameters dominates the survival of a nutrient (b-carotene) during a food processing step. A fluid carrying the nutrient is injected into the reactor, and is subsequently heated by a downstream cylinder. As b-carotene is heat sensitive it decomposes into fragments reducing the nutrient level of the fluid. The model starts with a screening study, followed by a sensitivity analysis, then looks at error propagation, and finally performs a reliability analysis.
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
- Module Uncertainty Quantification et
- soit le Module Battery Design, Module Chemical Reaction Engineering, Module Corrosion, Module Electrochemistry, Module Electrodeposition, ou Module Fuel Cell & Electrolyzer
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.
