Li, H. (author), Pourquie, M.J.B.M. (author), Ooms, G. (author), Henkes, R.A.W.M. (author)DNS and RANS simulations were carried out for core-annular flow in a horizontal pipe and results were compared with experiments carried out with water and oil in our lab. In contrast to most existing studies for core-annular flow available in the literature, the flow annulus is not laminar but turbulent. This makes the simulations more...journal article 2024

Li, H. (author), Pourquie, M.J.B.M. (author), Ooms, G. (author), Henkes, R.A.W.M. (author)The Reynolds-Averaged Navier Stokes (RANS) with the Launder & Sharma low-Reynolds number k−ε model was used to simulate core-annular flow in the same configuration with vertical upflow as considered by Kim & Choi (2018), who carried out Direct Numerical Simulations (DNS), and by Vanegas Prada (1999), who performed experiments. The DNS...journal article 2023

Li, H. (author), Pourquie, M.J.B.M. (author), Ooms, G. (author), Henkes, R.A.W.M. (author)Interfacial waves in core-annular pipe flow are studied through two-phase numerical simulations. Here the water annulus is turbulent, whereas the oil core stays laminar. The low-Reynolds number Launder & Sharma k−ε model is applied. By extracting the moving wave shape from the two-phase results and imposing this as a solid boundary in a...journal article 2022

Jiang, J. (author), Li, H. (author), Pourquie, M.J.B.M. (author), Ooms, G. (author), Henkes, R.A.W.M. (author)Core-annular flow is an efficient way of transporting viscous oil through a pipeline. A sharp increase in the pressure drop will occur when the oil waves at the water-oil interface touch the pipe wall. Depending on the oil and pipe material physical properties, the oil may adhere to the wall leading to fouling. Therefore, a necessary...journal article 2021

Li, H. (author), Pourquie, M.J.B.M. (author), Ooms, G. (author), Henkes, R.A.W.M. (author)1D, 2D and 3D numerical simulations were carried out with the Reynolds-Averaged Navier-Stokes equations (RANS) for horizontal oil-water core-annular flow in which the oil core stays laminar while the water layer is turbulent. The turbulence is described with the Launder-Sharma low-Reynolds number k−ϵ model. The simulation results are compared...journal article 2021
