The US Department of Energy’s Office of Fossil Energy (OFE) has named the University of Michigan as one of the recipients of a $5.4 million program to facilitate University research into high performance fossil fuel combustion turbines. Professor Venkat Raman and Associate Professor Mirko Gamba are the faculty leading the research at the University of Michigan, which will include further investigation on the operation and performance of rotating detonation combustors (RDCs). RDCs are novel combustor technologies based on the principle of pressure gain obtainable through a detonation-based combustion process. The study will address the fundamental question on how to operate and achieve performance gain on RDCs operated with realistic fuels. A high performing combustor will help DOE reach the target of improving the thermal efficiency of combined cycle gas turbine systems used for power generation to more than 65%. In turn, this will help reduce fuel consumption and mitigate emissions associated with fossil fuels.

Professor Raman’s research focuses on developing computational models for turbulent reacting flows, with applications to stationary power generation, as in the RDE; scramjet aircraft engines; and material synthesis. 

Professor Gamba’s research focuses on fundamental research in a diverse range of advanced and sustainable concepts for high speed propulsion and energy conversion systems.

Congratulations to both Professors as they continue their important work.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
