Since aerogel materials are open cell, inorganic foams, the surface pores of the material must be sealed for large scale application.

Here we discuss the design and development of a spout fluid bed system for producing coated aerogel particle material.

COMSOL Multiphysics was used in the design of the system to track the details of the flow field and individual aerogel particle trajectories.

The actual equipment design was incorporated into COMSOL using SolidWorks for a full 3-D simulation of the apparatus.
