Effect of mixed convection on laminar vortex breakdown in a cylindrical enclosure with a rotating bottom plate
Quaresma, JNN; da Cruz, CCS; Cagney, N; Cotta, RM; Balabani, S (Elsevier, 2020-01-01)© 2020 Elsevier Masson SAS Vortex breakdown plays a central role in the performance of countless rotating machinery applications, many of which contain thermal gradients either inadvertently or by design. The effect of ... -

Membrane fouling during the harvesting of microalgae using static microfiltration
Wu, J; Meeten, GH; Jones, TGJ; Cagney, N; Boek, ES (Elsevier, 2024-05-07)A challenge in the filtration of algal suspensions is the reduction in filtrate flow rate with time, associated with membrane fouling and filtercake formation. These two fouling mechanisms may occur simultaneously and have ... -
Mixing in flows past confined microfluidic cylinders: Effects of pin and fluid interface offsetting
Zhang, S; Cagney, N; Lacassagne, T; Balabani, S; Naveira-Cotta, CP; Tiwari, MK (Elsevier BV, 2020-10)Inserting obstacles such as cylindrical pins in a micromixer has the potential to significantly enhance scalar transport and improve species mixing between two co-flowing streams. However, it remains unclear how the mixing ... -

Modulation of elasto-inertial transitions in Taylor–Couette flow by small particles
Lacassagne, T; Boulafentis, T; Cagney, N; Balabani, S (Cambridge University Press (CUP), 2021-10-25)Particle suspensions in non-Newtonian liquid matrices are frequently encountered in nature and industrial applications. We here study the Taylor–Couette flow (TCF) of semidilute spherical particle suspensions (volume ... -
Probing vortex-shedding at high frequencies in flows past confined microfluidic cylinders using high-speed microscale particle image velocimetry
Zhang, S; Cagney, N; Balabani, S; Naveira-Cotta, CP; Tiwaril, MK (AIP Publishing LLC, 2019-10)Vortex-shedding from micropins has the potential to significantly enhance and intensify scalar transport in microchannels, for example by improving species mixing. However, the onset of vortex-shedding and the mixing ... -
