B. Mutlu Sumer is Professor at the Technical University of Denmark, Department of Mechanical Engineering, Section for Fluid Mechanics, Coastal and Maritime Engineering. He graduated with MSc (1967) and PhD (1970) from the Istanbul Technical University (ITU), Faculty of Civil Engineering. He was a post-doctoral research fellow at the University of Cambridge, UK (1971-1973). He was Professor of Hydraulics at ITU before he moved to Denmark in 1984. He has been with the Technical University of Denmark since then. His main fields of research are flow around marine structures –scour, liquefaction, forces, hydro-elastic vibrations-, and sediment transport. He has coordinated SCARCOST (Scour Around Coastal Structures) (1997-2000) and LIMAS (Liquefaction Around Marine Structures) (2001-2004), two European research programmes financed by the European Community under MAST III and FP5 programmes, respectively. He also has coordinated EPCOAST (Exploitation and Protection of Coastal Zones), a frame research program financed by Danish Technical Research Council (2005-2008), and Seabed Wind Farm Interaction, another frame research program financed by Danish Council for Strategic Research (DSF)/Energy and Environment (2008-2012). He is the author of three books: (1) B.M. Sumer and J. Fredsøe: Hydrodynamics Around Cylindrical Structures, World Scientific, 548 pp., 1997 (revised edition, 2006); (2) B.M. Sumer and J. Fredsøe: The Mechanics of Scour in the Marine Environment, World Scientific, 552 pp., 2002; and (3) B.M. Sumer: Liquefaction Around Marine Structures, World Scientific, 2014. He has published over 100 journal papers and over 80 conference papers on flow around and forces on marine structures, scour, liquefaction of marine soils, and sediment transport. He received 2005 ASCE Karl Emil Hilgard Hydraulic Prize.
Professor Sumer has done consultancy work for companies in Denmark and abroad on (1) scour/scour protection in connection with offshore wind farms, marine structures and pipelines; (2) wave-induced liquefaction of marine soils and its implication for marine structures; (3) forces on and vibrations of marine pipelines; and (4) river engineering and sediment transport.
1. Scour and scour protection around marine structures - Marine pipelines, slender piles, pile groups, large piles, offshore wind farms, subsea structures, breakwaters and complex structures.
2. Liquefaction of marine soils - Mechanics of liquefaction, sinking/flotation of marine objects in liquefied soil under waves, mathematical modeling of liquefaction, assessment of liquefaction potential under waves, pipeline floatation in liquefied soil in a trench, impact of earthquake-induced liquefaction on marine structures.
3. Wave boundary layers - Transition to turbulence, coherent structures, fully-developed turbulent wave boundary layers, combined wave and current boundary layers, effect of bed roughness, nonuniform boundary layers (convergent/divergent environment, sudden change in bed roughness), angle of attack, suction/injection (ventilated boundary layers), effect of externally generated turbulence.
4. Sediment transport, diffusion/dispersion - Longitudinal dispersion of sediment, settlement of solid particles, settling basins, bursting process/suspension mechanism, forces on sediment particles, instability of bedforms/ripple formation, sheet-flow regime sediment transport, influence of turbulence on bedload transport.
5. Flow around and forces on cylindrical structures and flow-induced vibrations - Forces on and vibrations of marine pipelines, correlation, vortex-flow regimes, effect of irregular waves.
