Experimental and numerical investigation of bubble migration in shear flow: Deformability-driven chaining and repulsion
(Journal article, 2023)We study the interaction-induced migration of bubbles in shear flow and observe that bubbles suspended in elastoviscoplastic emulsions organize into chains aligned in the flow direction, similarly to particles in viscoelastic ... -
Experimental and numerical investigation of nonlinear diffraction wave loads on a semi-submersible wind turbine
(Peer reviewed; Journal article, 2021)In a severe sea state, nonlinear wave loads can excite resonant responses of floating wind turbines either at high (structural) or low (rigid body motions) natural frequencies. In the present work, a computational fluid ... -
Experimental and Numerical Investigation of One-Dimensional Infiltration into Unsaturated Soil
(Chapter, 2021)Infiltration characteristics of an unsaturated soil are of interest in both seepage and stability analyses and should be evaluated carefully. In this study, a new large-scale one-dimensional infiltration column test setup ... -
Experimental and numerical investigation of residual stresses in proximity girth welds
(Peer reviewed; Journal article, 2023)International fabrication codes and standards provide minimum distance criteria for proximity welds, although rigorous justification is lacking. These distances are either based on practical experience or mutual agreement ... -
Experimental and Numerical Investigation of Sloshing under Roll Excitation at Shallow Liquid Depths
(Journal article; Peer reviewed, 2017)This paper investigates sloshing at shallow-liquid depths in a rectangular container by using experimental and numerical methods. A motion platform is used to perform a prescribed periodic rotational motion to excite the ... -
Experimental and numerical investigation of strain distribution of notched lead fatigue test specimen
(Journal article; Peer reviewed, 2018)The work here presented focuses on the test methodology related to effect of stress concentrators in strain controlled structures. Cable sheathing as used in subsea power cables are investigated by cyclic fatigue testing, ... -
Experimental and numerical investigation on a ejector for CO2 vapor compression systems
(Chapter, 2018)The use of two-phase flashing ejectors to improve the COP and capacity of CO2 vapor compression systems has become a key research topic in recent years. Although many experimental investigations focused on both the ejector ... -
Experimental and numerical investigation on the deformation behaviors of large diameter steel tubes under concentrated lateral impact loads
(Peer reviewed; Journal article, 2023)Large diameter steel tubes are widely used in bottom fixed and floating offshore wind turbines. Offshore wind turbines (OWTs) operating in the oceans are exposed to the risk of collisions when ships pass and dock at turbines. ... -
Experimental and numerical investigations of monopile ringing in irregular finite-depth water waves
(Journal article; Peer reviewed, 2017)In storm conditions, nonlinear wave loads on monopile offshore wind turbines can induce resonant ringing-type responses. Efficient, validated methods which capture such events in irregular waves in intermediate or shallow ... -
Experimental and numerical investigations of the water surface profile and wave extrema of supercritical flows in a narrow channel bend
(Journal article; Peer reviewed, 2024)Supercritical flows in channel bends, e.g., in steep streams, chute spillways, and flood and sediment bypass tunnels (SBTs), experience cross-waves, which undulate the free surface. The designs of these hydraulic structures ... -
Experimental and Numerical Modelling of Deep-Sea-Mining-Generated Turbidity Currents

Experimental and Numerical Results of a Non-DLE Aeroderivative GT Combustion System Burning Methane-Ammonia Blends at Intermediate Pressures
(Chapter, 2023)Ammonia is considered as a practical hydrogen carrier, as it can be stored in liquid form at moderate pressures and temperatures and is commonly produced and transported today. Ammonia could be used directly as a Gas Turbine ... -
Experimental and Numerical Studies of a High-Head Francis Turbine: A Review of the Francis-99 Test Case
(Peer reviewed; Journal article, 2016)Hydraulic turbines are widely used to meet real-time electricity demands. Computational fluid dynamic (CFD) techniques have played an important role in the design and development of such turbines. The simulation of a ... -
Experimental and numerical studies of the scattering of light from a two-dimensional randomly rough interface in the presence of total internal reflection: Optical Yoneda peaks
(Journal article; Peer reviewed, 2016)The scattering of polarized light from a dielectric film sandwiched between two different semi-infinite dielectric media is studied experimentally and theoretically. The illuminated interface is planar, while the back ... -
Experimental and numerical studies of tubular concrete structures subjected to blast loading
(Peer reviewed; Journal article, 2021)The E39 coastal highway route along the west coast in Norway is envisioned a future without ferries. A submerged floating tube bridge built in concrete has been suggested as a means of crossing wide and deep fjords, and ... -
Experimental and numerical studies on dynamic stress and curvature in steel tube umbilicals
(Peer reviewed; Journal article, 2020)The present paper addresses the stresses in dynamic steel tube umbilicals at the platform hang-off exposed to large motions corresponding to an extreme storm condition. Experimental tests were carried out by mounting ... -
