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
