Reduced flow drag by crystals
Reducing Flow Drag by Crystals

Profs. Hussein and Biringen established a new paradigm for passive flow stabilization to delay laminar-to-turbulent transition and reduce skin-friction drag. Their concept is based on extending the phenomenon of wave destructive interferences–traditionally observed only in solids–to the flow field. This novel approach is realized by interfacing the flow with an enlarged and carefully tuned crystal, also known as a phononic material. [Project funded by NSF]

Software Tools for Immersive Simulation

An NSF funded grant lead by Profs. Jansen, Doostan, Evans, and Maute focuses on the creation of software tools to enable immersive simulation, a new simulation paradigm which allows analysts to not only visualize system response but also interact with their system and modify boundary conditions, material, and geometry parameters during an ongoing massively parallel simulation.

One of four centers within the Department of Aerospace Engineering Sciences, the Aerospace Mechanics Research Center (AMReC) is concerned with the analysis and design of complex high-performance materials, structures and systems, predominantly for aeronautical and space applications. This includes the development of innovative computational analysis and design techniques as well as the application of these techniques and methods to novel, exciting aerospace problems.
