OPEN DAY 2019

March 2019

We can judge our progress by the courage of our questions and the depth of our answers, our willingness to embrace what is true rather than what feels good

- Carl Sagan

Open day, as the name suggests, is an occasion when IISc 'opens' its premises to all the curious and budding minds, presenting them with a golden opportunity to witness first-hand the plethora of diverse and original research transpiring in the Institute. Marked by a motley of scientific demonstrations, fun activities and simultaneous question and answer sessions, the students of the institute consider it both a moral and pedagogic responsibility to apprise the new generation of the current state-of-the-art, thereby inspiring the interested ones to pursue research in the future. Make no mistake, even the 'not-so-research-oriented' folks are welcome to drop by for some unprecedented fun and have a day off from their intense schedule.

The Laboratory for Hypersonic and Shock wave Research (LHSR) is dedicated to research in high-speed, high-enthalpy flows and collaborative work. We welcome one and all on Saturday, March 10, 2018 between 0900 to 1700 hrs to enjoy and learn from the miniature experiments planned in the Laboratory . It would be a privilege to cater to questions, so do not hesitate to 'ask to your heart's content'.

  • Hypersonic flow phenomena are necessary considerations in the engineering of any mission beyond the troposphere and back. With an ever-increasing focus on innovative means for access to space, hypersonic flows are at the forefront of research and development. Hypersonic flow problems are essentially multi-disciplinary since a host of issues need to be resolved - hightemperature gasdynamics, chemical and thermodynamic nonequilibrium, rarefied flow, aerodynamics, and heat transfer. They have a direct bearing on engineering aspects of thermal protection systems, futuristic propulsion systems, prediction of aerodynamic forces and control, and the communication blackout problem. Shock waves and their dynamics dominate hypersonic flow phenomena. Ground-based test facilities depend critically on the shock wave to generate hypersonic flow. Shock tubes are extensively used to characterize chemical kinetics at high pressures and temperatures. Astrophysical phenomena encounter hypersonic flows, and recent research traces the origins of life to shock wave phenomena. Recently, the impulsive nature and the capability to produce extreme pressure and temperature conditions have advanced the utility of shock wave phenomena in a plethora of applications including materials, lasers, nanotechnology, biotechnology, bio-medical applications, and several industrial uses. This symposium explores current developments enveloping all aspects of hypersonic and shock wave research.

  • The course gives brief introduction to the design and development of pulse detonation engines and air-breathing propulsion systems. Various topics ranging from the mission requirements for hypersonic flight vehicles, basic cycle designs and performance analysis methodology, design and development procedures, complex component interactions, recent computational and experimental results, major national air-breathing programs was covered along with some historical prospectives . Prof. Frank Lu, one of the most accomplished academician from the Dept. of Aerospace Engineering, University of Texas at Arlington, USA conducted this targeted training programme. The program was held during the 3-4 July 2017 in the Aerospace Department, Indian Institute of Science in association with Society for Shock Wave Research for the benefit of scientists and students.
