    • Abstract:
      "The project involved development of an agent-based computer model for transport of particulate matter in biofuel production systems, as well as application of this model to two different types of biofuel generation systems. The computational model examines particles of both spherical and non-spherical shape transported in a flow with complex geometry. The particles can be non-adhesive or adhesive, e.g., via van der Waals or liquid bridging adhesion. The agent-based model integrates to a finite-volume fluid dynamics code (U2RANS) to account for effects of particle transport in a flow. Applications of the computational method was made to: (1) combustion of biowaste particles, such as grain hulls or pellets, (2) separation of particles from the surrounding aqueous medium (de-watering), and (3) enhancement of algae growth rate in algae-based biofuel production systems. In the first application area, the particle agents in the model represent pieces of biowaste products, such as wood chips or grain hulls. In this part of the project, we shared our computer code with a collaborator at the University of Iowa specializing in combustion, and worked together with the investigators at Iowa to train a graduate student in using this code. The University of Iowa graduate student then used the code to compute biowaste particle combustion in a stoker burner, with comparison to experimental results obtained at Iowa."
