DNS of Wall-Bounded Turbulent Flows

Covers the topic of DNS from first principles, while relating this to the canonical problem of transition over zero pressure gradient boundary layer
Emphasizes the new subject of boundary layer receptivity over the classical topic of instability approach
Identifies spatio-temporal wave fronts to explain fluid flow phenomenon of transition that is unique and very revealing on the mechanism of transition

Prof. Tapan K. Sengupta, Ph.D. (Georgia Tech.) has devoted all his time in research and teaching of transition and turbulence, apart from his interest in aerodynamics. To aid in these research areas, he has developed scientific computing for fluid flow and wave phenomenon for more than three decades. He has written four single-author books in these subjects, apart from editing two more volumes on transition and high performance computing. He has been a Senior Research Associate in Univ. of Cambridge, Senior Visiting Fellow in National Univ. of Singapore, Senior Associate of the International Centre of Theoretical Physics (ICTP) at Trieste, Italy, visiting IdeX Professor of Excellence at Univ. of Bordeaux, France, Fellow at Univ. of Cambridge, UK at Murray-Edwards College and Univ. Engg., Department. He has been the Regional Editor of Computers & Fluids (Elsevier), New York, USA.
Dr. Swagata Bhaumik, PhD (IIT Kanpur, 2013) is currently visiting Assistant Professor, Department of Aerospace Engineering, IIT Kanpur. His PhD topic was: Direct Numerical Simulation of Transitional and Turbulent Flows, where he used his own developed high-accuracy 3D incompressible Navier-Stokes solver to investigate and characterize the dynamics of spatio-temporal wave-front and its role in causing flow transition. From 2014 to 2016 he was a Post-Doctoral researcher in the Ohio State University where he worked on the prediction and estimation of perfectly- and imperfectly-expanded jet noise. He has a Master's degree in Aerospace Engineering (Aerodynamics) from IIT Kharagpur (2007) and a Batchelor's degree in Mechanical Engineering from NIT Rourkela (2001).
