Complex flow physics
We study the dynamics of complex flows through integrated approaches combining physics-based modeling, high-performance computing and data science, software engineering, control, and companion experiments, with emphasis on rocket propulsion and hypersonics. We are also interested in cyberphysical integration - effectively connecting computers and real-world devices - to assimilate, control, and optimize engineering systems for existing and new applications. For any target system, we highly encourage addressing underlying flow physics; physical intuitions are often very useful for engineering optimization and error diagnostics.
