Scalar transport in inline mixers with spatially periodic flows
Başkan Perçin, Özge; Rajaei, Hadi; Speetjens, Michel F. M.; Clercx, Herman J. H. (2017-01-01)
Spatially persisting patterns form during the downstream evolution of passive scalars in three-dimensional (3D) spatially periodic flows due to the coupled effect of stretching and folding mechanisms of the flow field. Thi...
Experimental and numerical parametric analysis of a reoriented duct flow
Başkan Perçin, Özge; Speetjens, Michel F. M.; Metcalfe, Guy; Clercx, Herman J. H. (Elsevier BV, 2016-05-01)
This study concerns a coupled experimental-numerical analysis of scalar transport in reoriented duct flows found in industrial mixing processes. To this end the study adopts the Rotated Arc Mixer (RAM) as the representativ...
Experimental and computational study of scalar modes in a periodic laminar flow
Başkan Perçin, Özge; Speetjens, Michel F. M.; Metcalfe, Guy; Clercx, Herman J. H. (2015-10-01)
Scalar fields can evolve complex coherent structures under the action of periodic laminar flows. This comes about from the competition between chaotic advection working to create structure at ever finer length scales and d...
Direct experimental visualization of the global Hamiltonian progression of two-dimensional Lagrangian flow topologies from integrable to chaotic state
Başkan Perçin, Özge; Speetjens, M. F. M.; Metcalfe, G.; Clercx, H. J. H. (2015-10-01)
Countless theoretical/numerical studies on transport and mixing in two-dimensional (2D) unsteady flows lean on the assumption that Hamiltonian mechanisms govern the Lagrangian dynamics of passive tracers. However, experime...
Unravelling convective heat transfer in the rotated arc mixer
Speetjens, M.F.M.; Başkan Perçin, Özge; Metcalfe, G.; Clercx, H.J.H. (2014-01-01)
Thermal homogenization is essentially a transient problem and convective heat transfer by (chaotic) advection is known to accelerate this process. Convective heat transfer traditionally is examined in terms of heat-transfe...
