The National Science Foundation Division of Chemical, Bioengineering, Environmental, and Transport Systems awarded Purdue University a $242,730 Project Grant under the Engineering (47.041) federal grant program. The grant will support the development of new computational methods to conduct fast numerical simulations of low void fraction disperse multiphase systems using event-triggered communication. Specifically, the university researchers will apply ideas from control theory to speed up direct numerical simulations of disperse flows involving bubbles, drops, and particles suspended in another phase. With computational resources increasingly strained for simulations of systems with many concentrated particles, this research aims to reduce communication among parallel processing elements. The results should allow for more in-depth study of energy conversion, materials processing, and other industrial and natural disperse multiphase systems critical to technology and living systems. Findings may also yield novel computational strategies to improve parallel processing efficiency for such simulations.
