Distinguished Fellow: U.S. Navy - ASEE
Research Interests:
turbulence in rotating flows, wakes, corner flows
transition and transient flows in turbomachinery
erosion - corrosion - deposition from contaminated hot gas flows
Professor Raj has published more than sixty papers in the areas of turbomachinery. He developed for the first time the turbulence dissipation equation applied to rotating flows and showed that it is not independent of rotation. His wake models related to cascade, rotors and free stream turbulence are first in the field of turbomachinery. He was appointed twice fellow of NASA and thrice the distinguished fellow of U.S. Navy. At NASA his work involved new fuels in space for long range flights. While he was in the Navy his work involved advanced launching systems, sonar, and transient flow pumps. He has collaborated extensively with industry in the areas of erosion, corrosion and deposition from highly contaminated, high temperature gas flows and development of high temperature new turbine. He has also examined most fundamental problems; transition from conservative to non- conservative field, highly accelerating rotating flows, ram- pump- mid stroke rumble, and concepts beyond relativity. He has served as a consultant to the United Nations in the field of turbomachinery.
