Popular talk of NASA scientist Dr. P. Balakumar at Department of Interdisciplinary Studies

Dr. Ponnampalam Balakumar (Research scientist at NASA Langley Research Center) delivered a popular talk about “stability-transition-turbulence” on 10th of January, 2018 at Department of Interdisciplinary Studies. This talk was jointly organized by Mechanical Engineering Society (MES), Faculty of Engineering and Vadakkin Chapter of Institution of Engineers, Sri Lanka (IESL). This talk was mainly focus on his work done in NASA Langley Research Center. He discussed elaborately about the stability and transition of hypersonic boundary layers and laminar-transition region in supersonic and hypersonic flows.

Dr. Ponnampalam Balakumar graduated from University of Peradeniya in 1977 from Department of Civil Engineering. He obtained his MS degree in Mechanical Engineering from University of Missouri, Rolla, USA in 1981 and obtained his PhD in Aeronautics from MIT in 1986 specializing in Fluid Dynamics. He did his post-doctorate research in stability and transition of hypersonic boundary layers at Arizona State University, USA. Then, he worked as an Associate Professor at Old Dominion University until 2000. Since then he is working as a Research Scientist at NASA Langley Research Center. His area of research is stability, transition, and turbulence of supersonic and hypersonic boundary layers.

Abstract: Drag reduction is an important part in design of aerodynamic vehicles. Skin friction drag contributes more than 50% of the total drag on an aircraft. Skin friction drag reduction could be achieved by extending the laminar region on an airfoil and/or by reducing the turbulent skin friction. In this talk, a summary of predicting the laminar-transition region in supersonic and hypersonic flows will be discussed.

Faculty Staff and students Members participated to the Civil Engineering Research Symposium at University of Ruhuna

The Civil and Environmental Engineering Society of the University of Ruhuna, hosted Undergraduate Research Symposium on the 3rd of January 2018. Total of 10 Civil and Environmental Engineering Society of University of Jaffna together with two staff members, Dr. N. Sathiparan and Dr. D.N. Subramaniam (who were in the evaluation panel, and one of them Chaired a technical presentation session), attended the sessions. The research symposium highlighted the undergraduate student research projects, which were part of their curriculum, with oral and poster presentations. Several members from different Universities, industrial engineers, policy makers and professionals attended the sessions.
