Development of an efficient two-phase 3D numerical wave flume
(Society of Petroleum Engineers, 2017)In the present study an efficient two-phase 3D numerical wave flume was developed, tested and validated. The most important advantage over conventional numerical wave flumes is the use of a constant coefficient Poisson ...

Effect of turbulent pulsating flow around a near-wall submerged cylinder on the potential motion of bed and suspended loads
(International Society of Offshore and Polar Engineers, 2016)In the present work, the pulsating flow around a submerged cylinder close to the impermeable seabed is examined by means of Large Eddy Simulations (LES). A Reynolds number equal to Re = 5000 is considered, based on the ...

Photothermal measurements of differential reflectivity of YBCO related to the symmetry of the superconducting order parameter
(1996)We have investigated symmetry of the differential optical response of single YBCO domains in the a-b plane. As a function of temperature, this response consists of a smooth background and a sharp peak in the vicinity of ...

Vortex liquid state in an electron irradiated untwinned YBa2Cu3O7-δ crystal
(1995)We report on the temperature and field dependencies of the resistivity of an untwinned YBa2Cu3O7-δ single crystal before and after 1 MeV electron irradiation in fields up to 8 T. We show, for the first time, direct suppression ...
