Method for reconstruction of axisymmetric capillary wave surface topography using inverse ray-tracing of refracted laser sheet
Mukim, Vineet Vishnu; Time, Rune Wiggo; Kanade, Udayan Rajendra; Rabenjafimanantsoa, Herimonja Andrianifaliana (Peer reviewed; Journal article, 2022)Capillary waves can be used to measure the fundamental fluid properties such as surface tension as well as, potentially, the viscosity of Newtonian fluids. This requires the measurement of various wave parameters, mainly ... -
Oscillating Flow and Pressure Drop in Horizontal Pipes
Albriktsen, Mikela (Master thesis, 2022)The study’s main aim is to evaluate oscillating flow and pressure drop in horizontal pipes. First, the equipment is calibrated to ensure the correct flow rate. Calibra- tion is done with three methods. These are, Calibration ... -
Particle Settling in shear thinning non-Newtonian drilling fluids : Effect of oscillatory motion
Amaratunga, Polwattage Don Malitha Maduranga (PhD thesis UiS;537, Doctoral thesis, 2020-09)When drilling fluids circulate through the well and during the solids control operations, they are exposed to vibrations and oscillations of different frequencies and amplitudes. The secondary flow structures in oscillatory ... -
Small scale thermohaline ocean circulation
Wanyenze, Joan Shanita (Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-15)Upon examining the how convective flows are generated in the ocean, Henry Stommel presented a simple idealized model called the Stommel model (1961) to better understand how salinity and temperature differences can affect ... -
Whirling dynamics of a drill-string with fluid–structure interaction
Volpi, Lucas; Cayeux, Eric; Time, Rune Wiggo (Peer reviewed; Journal article, 2023)Fluid–structure interaction models for drill-string vibrations are often of reduced order. However, both the structure and the surrounding fluid are non-linear, which can lead to complex coupled dynamic. In this paper, a ...
