Dr Valentin Heller, Dr sc ETH Zurich, Dipl Bau-Ing ETH (MSc/BSc) (Civil Engineering)

Introduction

Dr Valentin Heller is currently an Assistant Professor in Hydraulics in the Department of Civil Engineering at the University of Nottingham and a member of the Geohazards and Earth Processes 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. His research mainly concerns experimental fluid dynamics into landslide-tsunamis (impulse waves), marine renewables and scale effects in fluids and granular slides. Dr Heller and his research team further apply a wide range of computational fluid dynamics CFD, and other, codes such as DualSPHysics, OpenFOAM, SWASH and LIGGGHTS-DEM.

Wave energy conversion

Landslide-tsunamis (impulse waves)

Scale effects

Ski jump hydraulics

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.

 

 

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.

Dr Heller is interested in many further research areas including shallow-water vortices, viscoelastic material behaviour, development of measurement systems and beach reflection analysis.
