Blishchik, A. (author), Glavinić, Ivan (author), Wondrak, Thomas (author), van Odyck, Daniel (author), Kenjeres, S. (author)In the present study, we have performed a series of numerical simulations of the turbulent liquid metal flow in a laboratory-scale setup of the continuous casting. The liquid metal flow was subjected to an external non-uniform magnetic field reproducing a realistic electromagnetic brake (EMBr) effect. The focus of this research was on the...journal article 2022

Blishchik, A. (author), van der Lans, Mike (author), Kenjeres, S. (author)There is a continuous need for an updated series of numerical benchmarks dealing with various aspects of the magnetohydrodynamics (MHD) phenomena (i.e. interactions of the flow of an electrically conducting fluid and an externally imposed magnetic field). The focus of the present study is numerical magnetohydrodynamics (MHD) where we have...journal article 2021

Kura, Tomasz (author), Fornalik-Wajs, Elzbieta (author), Wajs, Jan (author), Kenjeres, S. (author)The jet impingement phenomenon plays an important role among the heat transfer intensification methods. Very often its application and analyses refer to simple flat surfaces, while there is a lack of information in the literature for cases addressing curved surfaces. In the present work, the single jet impingement on the non-flat (concave and...journal article 2021

Chakkingal, M. (author), Schiavo, Sabino (author), Ataei Dadavi, I. (author), Tummers, M.J. (author), Kleijn, C.R. (author), Kenjeres, S. (author)We numerically investigate natural convection in a bottom-heated top-cooled cavity, fully and partially filled with adiabatic spheres (with diameter-to-cavity-size ratio d/L=0.2) arranged in a Simple Cubic Packing (SCP) configuration. We study the influence of packing height and location of porous media. We carry out the simulations using...journal article 2020

Chakkingal, M. (author), Kenjeres, S. (author), Ataei Dadavi, I. (author), Tummers, M.J. (author), Kleijn, C.R. (author)We report numerical simulations of natural convection and conjugate heat transfer in a differentially heated cubical cavity packed with relatively large hydrogel beads (d/L=0.2) in a Simple Cubic Packing configuration. We study the influence of a spatially non-uniform, sinusoidally varying, wall temperature on the local flow and heat transfer...journal article 2020
