Experimental data on filling and emptying of a large-scale pipeline
Autor: Xifeng Chen, Qingzhi Hou, Janek Laanearu, Arris S. Tijsseling
Publikováno v: Scientific Data, Vol 11, Iss 1, Pp 1-9 (2024)
Abstract Laboratory-scale experiments are one of the most important means to explore the evolution of air-water interfaces and the mechanisms of pressure oscillations in pipelines during rapid filling and emptying processes. This study presents a dat

Three-dimensional CFD analysis of liquid slug acceleration and impact in a voided pipeline with end orifice
Autor: Junling He, Qingzhi Hou, Jijian Lian, Arris S. Tijsseling, Zafer Bozkus, Janek Laanearu, Lei Lin
Publikováno v: Engineering Applications of Computational Fluid Mechanics, Vol 16, Iss 1, Pp 1444-1463 (2022)
This research describes the dynamic behavior of an isolated slug driven by pressurized air in a voided line with an end orifice. A three-dimensional (3D) computational-fluid-dynamics (CFD) model is used to simulate the rapid propulsion and impact at

Experimental study of eddy viscosity for breaking waves on sloping bottom and comparisons with empirical and numerical predictions
Autor: Nelly Oldekop, Toomas Liiv, Janek Laanearu
Publikováno v: Proceedings of the Estonian Academy of Sciences, Vol 68, Iss 3, Pp 299-312 (2019)
Focus is on the turbulence for a plunging breaker. Laser Doppler anemometer point measurements were used to determine the velocity matrix of a breaking wave on a sloping bottom. Using the Reynolds stress anisotropy for incompressible fluid, it was fo

Rotational effects on exchange flows across a submerged sill
Autor: Jarle Berntsen, Alan Cuthbertson, Janek Laanearu, Magdeli Asplin
Publikováno v: Environmental Fluid Mechanics
This paper presents new laboratory-scale numerical simulations of density-driven exchange flows generated across an idealised, submerged sill obstruction under both non-rotating and rotating frames of reference using the Bergen Ocean Model (BOM), a t
