“…In a first step we addressed this multiphase flow configuration by conventional CFD simulations, modelling the two stratified fluids (metal and slag) by a Volume of Fluid (VoF) method, the bubble plumes by tracking representative Lagrangian parcels of bubbles and fluid turbulence by a coarse grained Large Eddy Simulation (LES). More details on this modelling concept and on cold-water validation experiments with the aim to study converter oscillations can be found in Pirker et al (2012).…”

Classical Computational Fluid Dynamics (CFD) of long-time processes with strongly separated time scales is computationally extremely demanding if not impossible. Consequently, the state-of-the-art description of such systems is not capable of real-time simulations or online process monitoring.In order to bridge this gap, we propose a new method suitable to decouple slow from fast degrees of freedom in many cases. Based on the recurrence statistics of unsteady flow fields, we deduce a recurrence process which enables the generic representation of pseudo-periodic motion at high spatial and temporal resolution.Based on these fields, passive scalars can be traced by recurrence CFD. While a first, Eulerian Model A solves a passive transport equation in a classical implicit finite-volume environment, a second, Lagrangian Model B propagates fluid particles obeying a stochastic differential equation explicitly.Finally, this new concept is tested by two multiphase processes -a lab scale oscillating bubble column and an industrial scale steelmaking converter. Results of tracer distribution obtained by recurrence CFD are in very good agreement with full CFD simulations, while computational times are dramatically reduced. Actually, recurrence CFD is a promising candidate for online simulations of passive transport processes at full CFD resolution, which opens the door towards improved process monitoring.

“…Many researchers have studied this phenomenon in the past few decades to estimate liquid free surface or pressure in different storage tank geometric shapes. Choun and Yun [1], Chen and Chiang [2], Celebi and Akyildiz [3], Frandsen [4], Akyildiz and Unal [5,6], Chen and Nokes [7], Wu [8], Lee et al [9,10], Liu and Lin [11], Panigrahy et al [12], Belakroum et al [13], Ming and Duan [14], Huang et al [15], Jung et al [16] and Pirker et al [17] studied the sloshing phenomenon in rectangular tanks. Wu [8] studied probability of exciting second-order resonance in a rectangular tank in horizontal motion and its relation to natural frequencies of the tank.…”

“…Their method was pure numeric, and the optimization was based on the vibration suppression of the liquid motion. Although the problem is a classic case [12][13][14][15][16][17][18][19][20][21][22][23][24][25], the study of its exergy is discussed comprehensively in rare studies [1,26]. The entropy analysis of the flow systems is performed in many flow motions [27][28][29][30][31][32][33][34], as well and the recent developments in fluid modeling [35][36][37][38][39].…”

In this manuscript, the optimal design of geometry for a forced sloshing in a rigid container based on the entropy generation minimization (EGM) method is presented. The geometry of the vessel considered here is two dimensional rectangular. Incompressible inviscid fluid undergoes horizontal harmonic motion by interaction with a rigid tank. The analytical solution of a fluid stream function is obtained and benchmarked by Finite element results. A parameter study of the aspect ratio, amplitude, and frequency of the horizontal harmonic motion is performed. As well, an analytical solution for the total entropy generation in the volume is presented and discussed. The total entropy generation is compared with the results of the Reynolds-Averaged Navier–Stokes (RANS) solver and the Volume-of-Fluid (VOF) method). Then, the effect of parameters is studied on the total entropy generated by sway motion. Finally, the results show that, based on the excitation frequency, an optimal design of the tank could be found.
