Cfd analysis of low frequency oscillations in Newtonian and non-Newtonian fluids in a vertical pipe
Amaratunga, Polwattage Don Malitha Maduran; Rabenjafimanantsoa, Herimonja Andrianifaliana; Time, Rune Wiggo (Peer reviewed; Journal article, 2019)The effect of vertically imposed, low frequency oscillations on the rheology of shear-thinning non- Newtonian fluids are studied numerically by computational fluid dynamics (CFD). Both Newtonian (water) and inelastic ... -
Computational fluid dynamics simulation of buoyant mixing of miscible fluids in a tilted tube
Ghorbani, Maryam; Giljarhus, Knut Erik Teigen; Skadsem, Hans Joakim; Time, Rune Wiggo (Peer reviewed; Journal article, 2021)Buoyancy-driven flows and mixing of fluids with different densities occur frequently both in nature and as part of industrial processes within chemical and petroleum engineering. This work investigates the buoyant exchange ... -
Influence of low-frequency oscillatory motion on particle settling in Newtonian and shear-thinning non-Newtonian fluids
Amaratunga, Polwattage Don Malitha Maduran; Rabenjafimanantsoa, Herimonja Andrianifaliana; Time, Rune Wiggo (Peer reviewed; Journal article, 2021-01)An experimental study is performed to observe the effect of vertical fluid oscillations on the mean settling velocity of single spherical glass particles released into mixtures of water and polymeric fluids which exhibit ... -
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 ... -
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 ...
