Additive Manufacturing for Energy


Supervising Faculty: Dr. Suresh Babu

Narendran Raghavan is working with commercial, residential and industrial energy efficiency group at ORNL. His main research interest is in the field of industrial energy efficiency. He is also interested in working on renewable energy technologies, building energy efficiency and additive manufacturing. He holds bachelor`s degree in electronics and communication engineering from college of engineering Guindy, Chennai, India. He worked for IBM India over an year before joining University of Dayton in 2011 and obtaining his Master`s degree in renewable and clean energy in 2013.


Understanding the process - structure relationship through control and optimization of scan strategy in metal additive manufacturing (3-D printing) for on-demand, site-specific solidification microstructure (grain morphology) control. A parallel, heat transfer and fluid flow solidification code is employed to understand and optimize the scan strategy. The results from numerical models are coupled with phenomenological models. Processing strategy is modified accordingly to control the solidification grain size and morphology as and when required. Coupled experimental and modeling work is performed at Manufacturing Demonstration Facility (MDF) at Oak Ridge National Laboratory.  A demonstration aerospace component has been additively manufactured with on-demand, hybrid grain morphology (Columnar and Equiaxed). It is one of the pioneering breakthroughs in the field of metal additive manufacturing. Overall, this work employs a combination of experimental, characterization and numerical modeling framework.
