Cascioli, E. (author), Keijers, S. (author), Van Tichelen, K. (author), Vesper, J.E. (author), Kenjeres, S. (author)In the present work, we have applied a combined dynamic large-eddy simulation (LES) and direct numerical simulation (DNS) approach for a three-dimensional planar jet in a turbulent forced convection regime (Re = 18000) with a heated co-flow. Results from LES are compared with Reynolds Averaged Navier-Stokes (RANS) simulations and experimental...journal article 2022

Righolt, B.W. (author), Kenjeres, S. (author), Kalter, R. (author), Tummers, M.J. (author), Kleijn, C.R. (author)We demonstrate how the self-sustained oscillation of a confined jet in a thin cavity can be quantitatively described by a zero-dimensional model of the delay differential equation type with two a priori predicted model constants. This model describes the three phases in self-sustained oscillations: (i) pressure driven growth of the oscillation, ...journal article 2015

Kuhn, S. (author), Kenjeres, S. (author), Von Rohr, P.R. (author)In this numerical study the mixed convective flow of water over a heated wavy surface over a range of Reynolds and Richardson numbers, including transitional and turbulent flow regimes (20 ? Re ? 2000 and 0.5 ? Ri ? 5000) is investigated. A dynamic Large Eddy Simulation (LES) approach is applied where the thermal buoyancy effects are represented...journal article 2009
