Quantitative imaging of the air-water flow fields formed by unsteady breaking waves
… measuring the velocity fields on the air and water side of unsteady breaking waves is presented. The method is applied to breaking waves to investigate the physics of the air and water flow fields to further our knowledge of the impact of wave breaking on air-sea interaction. The …

Experimental investigation of small-scale breaking waves : flow visualization across the air-water interface
… dynamics of breaking waves significantly affect air-sea fluxes of heat, momentum, mass and energy across the ocean interface. Breaking waves also contribute considerable loading to offshore and coastal structures, and furthermore, the quasi-steady bow wave on a ship increases drag and ease of …

Hydraulisches Verhalten von Treppengerinnen mit eingetieften Stufen : selbstinduzierte Abflussinstationaritäten und Energiedissipation
… frequently utilized by dams to spill floodwater defined by the existence of endsills or weirs perpendicular to the flow at the end of each step. Weirs increase the energy dissipation and can cause the formation of unsteady flow, therefore the steady inflow of the flat stepped chutes was …

Flow patterns in upward two-phase flow in small diameter tubes
Two-phase flow in small tubes and channels is becoming a common phenomenon in industrial processes. However, the study of two-phase flow regimes in small tubes is still at its infancy. The previous studies are reviewed and discussed in the literature section. The problems and inconsistencies …

Experimental Investigations of Internal Air-water Flows
… techniques to the study of gas-liquid pipe flows, with a focus on conditions occurring in header-feeder systems of nuclear reactors under different accident scenarios. Novel experimental techniques have been proposed for the identification of the flow regime and measurement of the flow rates …

Simulation and Validation of Two-Component Flow in a Void Recirculation System
… core in case of an accident. Occasionally, air is entrained into the suction piping of ECCS causing voids that decrease pumping efficiency, and consequently damage the pumps. In an attempt to minimize the amount of voids entering the suction side of the pump in ECCS, a Void Recirculation …

Flow patterns on sieve trays
Studies into gas-liquid flow patterns were carried out on commercial scale sieve trays where the ratio of froth depth to flow path length is typical of that found in practice. Experiments were conducted on a 2.44 m diameter air-water distillation simulator, in which flow patterns were investigated …

Numerical investigation of the fluidelastic instability of two-phase flow in a parallel triangular tube array
… always susceptible to vibrations induced by the flow in either the shell or tube sides. The fluidelastic instability phenomenon (FEI) is considered one of the most devastating flow excitations since it may cause excessive wear and structural failure to the tubes in a short time span, yet the …

Investigation of Swirl Flows Applied to the Oil and Gas Industry
Understanding how swirl flows can be applied to processes in the oil and gas industry and how problems might hinder them, are the focus of this thesis. Three application areas were identified: wet gas metering, liquid loading in gas wells and erosion at pipe bends due to sand transport. For all …

Micromechanical study of two-phase flow during air sparging
Air sparging (AS) is an in-situ soil/groundwater remediation technology, which involves the injection of pressurized air/oxygen through an air sparging well below the region of contamination. The efficiency of the in-situ sparging system is mainly controlled by the extent of contact between …

Modelling of the liquid slag behaviour in the continuous casting mould
… of argon bubbles and their influence on the flowfield (mainly due to buoyancy) in conjunction with the fluctuating surface dynamics. The bulk of the research concerns comparisons against flowfield and interface data obtained from an experimental water/oil study of the process. However, the …
