Introduction |
|
Dr Valentin Heller is currently an Associate Professor in Hydraulics in the Department of Civil Engineering at the University of Nottingham and a member of the Environmental Fluid Mechanics and Geoprocesses Research Group. Before moving to the University of Nottingham, he held one of the prestigious Imperial College London Research Fellowships, a Research Fellowship at the University of Southampton and a postdoctoral position at ETH Zurich. He received his PhD and MSc in Civil Engineering from ETH Zurich. Dr Heller is mainly active in Experimental and Computational Fluid Dynamics with applications into fluid-structure interactions from small to very large scale. The fluid is typically water and the structure a hydraulic structure such as a dam, wall, landslide or iceberg. His research team applies a wide range of measurement systems (Particle Image Velocimetry, laser distance sensors, load cells) and open source codes such as DualSPHysics, OpenFOAM, SWASH and LIGGGHTS-DEM. Recent research applications in coastal and hydraulic engineering include wave-flexible-structure interaction, iceberg-tsunamis, novel scaling laws in air-water flows, scale effects in granular slides or the effect of the water body geometry and bathymetry on landslide-tsunamis. |

Wave energy converters WECs are used to transform wave power in electrical power. Dr Heller is particularly interested in the verification of the concept and theory of distensible WECs.
|
|
Landslide-tsunamis are generated by mass movements such as landslides, rock falls or glacier calving. Dr Heller is interested in physical and numerical modelling of such extreme waves and completed a number of project including Landslide-tsunamis (impulse waves), The Leverhulme Trust project, a NERC project (geometrical effects on landslide-tsunamis) and Wave-structure interaction.
|
|
Scale effects arise due to forces which are too dominant in a physical scale model compared to its prototype and they may result in significant deviations between the up-scaled model and prototype observations. Several on-going and past projects of Dr Heller address scale effects in fluids and granular slides. |
|
Ski jumps are employed downstream of dams to deflect large discharges from floods into the tail water. Dr Heller conducted generic physical model tests involving different types of flip buckets, the main element of ski jumps. |
