Stefan Braun

Stefan Braun is an Associate Professor at the Vienna University of Technology (TU Wien) in the Department of Fluid Mechanics, where he has been employed since 2003. He previously served as a Visiting Professor at the University of Manchester's School of Mathematics in 2006. His academic qualifications include a Dipl.-Ing. in Physics (1986-1992), Dr.techn. (1993-1997), and Habilitation (1998-2003), all completed at TU Wien.

His research focuses on applied mathematics in fluid mechanics, specializing in asymptotic methods for boundary layer analysis including flow separation and transition phenomena. Additional expertise includes spectral methods for PDEs and industrial applications of coupled heat/mass/momentum transfer. Current investigations span transitional separation bubbles, boundary layer singularities, and multiphase flow modeling.

His recent publications demonstrate strong emphasis on boundary layer theory, with 75% of his last 15 articles focused on separation phenomena, transition physics, and asymptotic methods. Industrial applications include fuel cell modeling and multiphase flow in champagne bottle dynamics.

He has supervised 14 graduate students including Dominik Kuzdas, Florian Altmann, and Lukas Wagner. Student theses cover topics from transitional separation bubbles to fuel cell modeling and multiphase flows.

He leads research activities within the Fluid Mechanics group at TU Wien, collaborating with institutions including the University of Manchester. Current projects involve numerical simulations of boundary layer transitions and industrial fluid applications.
