Lars Larsson
Lars Larsson is Full Professor of Hydrodynamics at Chalmers since 1982. He has a keen interest in international cooperation and was a member of the ITTC Resistance Committee for many years. He is the initiator of a series of Workshops on Hydrodynamics CFD, where the state-of-the-art is assessed every five years. During the past 30 years the Workshops have alternated between Gothenburg and Tokyo. Prof. Larsson has also been an active participant in many EU-sponsored projects from the mid-1990s, where most organizations in Europe engaged in Hydrodynamics CFD have participated. A sailor since birth Prof. Larsson has been engaged as a design consultant in five America's Cup campaigns in Sweden, USA and Italy. He is also the author (together with Rolf Eliasson, 2007) of the book Principles of Yacht Design and (with Hoyte Raven, 2010) of Ship Resistance and Flow. Prof. Larsson was Head of the Department of Naval Architecture and Ocean Engineering 1999-2005 and vice Head and responsible for the Graduate Program at the Department of Shipping and Marine Technology 2006-2009. In 2002-2010 he was also the Director of the Rolls-Royce University Technology Centre in Computational Hydrodynamics at Chalmers. Prof. Larsson had a leading role in the introduction of Computational Fluid Dynamics (CFD) in Naval Architecture and he is the founder of the CFD software company FLOWTECH International AB, for which he is presently Chairman of the Board. During the period 1971-1989 he was a research engineer at the maritime consulting company SSPA in Gothenburg. He recived his MSc in Naval Architecture from Chalmers in 1969 and has a PhD in Applied Thermo and Fluid Dynamics from Chalmers in 1975.
