About the Author: Prof. Sengupta received his basic aeronautical/aerospace education from IIT Kharagpur, IISc Bangalore and Georgia Tech., Atlanta, USA. He has worked in various research organizations and educational institutes at NAL Bangalore, India; Univ. of Cambridge, U.K.; National University of Singapore, Singapore and IIT Kanpur, where he currently holds the PR Dwivedi Chair apart from leading HPCL, IIT Kanpur. His research interests span across fields of scientific and high performance computing; fundamental fluid mechanics and aerodynamics; transition and turbulence. His research teams have refined and expanded areas of scientific computing, HPC, receptivity/instability, transition and turbulence. His interests in fundamental aspects of aerodynamics have resulted in this book containing classical theoretical analyses and newer topics of transonic aerodynamics; natural laminar flow airfoil analysis and design; low Reynolds number aerodynamics; flow control to delay transition and separation. These later topics are outcome of his contributions in direct numerical simulation (DNS) and large eddy simulation (LES).
