Simulation and Modeling


Cellencor uses COMSOL Multiphysics® to perform electromagnetic simulations of microwave cavities, applicators, and antennas.  COMSOL Multiphysics® is a powerful finite element multiphysics simulation software suite that can be used to model and simulate various microwave heating applications. Sometimes we receive basic questions that are specific to a customer's application, and COMSOL® allows us the flexibility of testing new ideas without  many of the negatives of testing it via trial-and-error.

Practical Example

For example, we have a customer with a system in place who determined that their product quality greatly improved when it was exposed to a large amounts of microwave energy in the beginning of their process, and then finished with much lower power. One low cost way this could be achieved was to add a metal wall or partition inside of their oven as opposed to adding a new cavity in series with the existing system. We turned to computer simulation to validate whether this method could work as expected to solve their problem, and quantify the power attenuation that would result from including a partition inside the center of the microwave cavity. The picture below shows how effective modeling can be at validating an idea before any metal was cut or welds were made, saving time and money and more importantly solving the customers problem.


                          No Partition                                             Partition                                                                                               





COMSOL Multiphysics Modeling and Hot spots

Another application for computer modeling has been designing custom multi-mode cavities that distribute energy evenly to help alleviate hot and cold spots in the energy fields. Below is a picture of how the energy density changes with microwave frequency. The video below that shows real-world testing validating the models predictions.
