As particulate matter moves within a fluid flow, the properties of the particles and the particle-fluid interface impact the phenomena that develop. Multi-component discrete particulates may be used to control or alter the particle properties during transport. Multi-component particulates might include particles formed from different layers of solid materials or containing encapsulated liquids, potentially phase changing materials, particles containing multiple particles, an agglomerate, or embedded particulates. During the fluid flow, phase change, reactions, or other effects might be initiated, potentially altering the material exposed to the flow, causing heat and mass transfer at the particle interface, or changing the internal properties, heat transfer, and mass transfer. The results may include changes in the rates of reactions or phase change, introduction of a new material to the flow, variation in the fluid or particle properties, delivery of a certain material, or some other useful effect. This work will present a computational fluid dynamics technique developed to simulate multi-component particulate or material within a gas flow through three different multi-component configuration examples. Through this discussion, the capabilities of the modeling method will be demonstrated.
