Immersed Boundary Method

Somnath Roy is an Associate Professor at Indian Institute of Technology Kharagpur. Dr. Roy received his Masters’ degree in Mechanical Engineering from IIT Kanpur in 2004, and Ph.D. degree in Mechanical Engineering from Louisiana State University, USA in 2010. Before joining IIT Kharagpur, he worked as a research associate and visiting Assistant Professor at Louisiana State University, USA and as an Assistant Professor at Indian Institute of Technology Kharagpur. His research interest is turbulence, arterial flows, moving boundary flow simulation, high performance computing using cluster and GPGPUs. His primary area of work is computational fluid dynamics (CFD). He has hosted two GIAN programs on computational methods and has also offered online course (NPTEL) on matrix solvers. His group works on developing immersed boundary method (IBM) based computationally efficient algorithms to solve moving boundary problems and on utilizing these implementations to predict flow and heattransfer in engineering and biological applications.  Ashoke De is currently working as Associate Professor in the Department of Aerospace Engineering at Indian Institute of Technology Kanpur. Dr. De received his Masters’ degree in Aerospace Engineering from IIT Kanpur in 2004, and Ph.D. degree in Mechanical Engineering from Louisiana State University, USA in 2009. Before joining IIT Kanpur, he worked as a post-doctoral scholar at Technical University of Delft (TU-Delft), Netherlands and as Research Engineer in GE Global Research at Bangalore. He is the recipient of many awards and fellowships including the Humboldt Research fellowship (2018), DAAD Fellowship (2016) and GE Global Research’s Expertise Award (2010), among others. Dr. De leads large-scale initiatives in the modeling of turbulent reacting and non-reacting flows at IIT Kanpur. His current research interests include combustion modeling, hybrid RANS/LES model development, supersonic flows and Fluid-Structure interactions (FSI). His primary research focus is the emerging field of computational mechanics with particular interest in combustion and turbulent flows.Elias Balaras is a Professor at the Department of Mechanical and Aerospace Engineering at George Washington University. Prof. Balaras received his Ph.D. from the Swiss Federal Institute of Technology (EPFL) in Lausanne, Switzerland in 1995. He was formerly a visiting scientist at the National Institute for Standards and Technology and a faculty at the University of Maryland. Prof. Balaras's current research program aims at the development of robust numerical techniques for parallel, large-scale simulations of multiscale, multiphysics problems in physical and biological systems. Emphasis is given at large-eddy and direct numerical simulations, fluid-structure interactions and biological fluid dynamics. He has been the recipient of several awards including the Marie-Curie fellowship from the European Commission in 1994and the career award from the National Science Foundation in 2003. He is currently an Associate Editor at the ASME J. Fluids Engineering and has served as a reviewer for numerous journals and government programs related to fluid mechanics, biological flows, high performance computing and turbulence.
