Experimental insights into elasto-inertial transitions in Taylor-Couette flows
Boulafentis, T; Lacassagne, T; Cagney, N; Balabani, S (2023) -
Flow dynamics and mixing past pairs of confined microfluidic cylinders
Zhang, S; Han, Y; Lacassagne, T; Cagney, N; Naveira-Cotta, CP; Balabani, S; Tiwari, MK (2023) -
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 ... -
Shear-thinning mediation of elasto-inertial Taylor-Couette flow
Lacassagne, T; Cagney, N; Balabani, S (Cambridge University Press, 2021-03-24)We study the shear-thinning mediation of elasto-inertial transitions in Taylor-Couette flow of viscoelastic polymer solutions. Two types of high molecular weight polymers are used at various concentrations and in water-glycerol ... -
Taylor-Couette flow of polymer solutions with shear-thinning and viscoelastic rheology
Cagney, N; Lacassagne, T; Balabani, S (Cambridge University Press, 2020-01-01)We study Taylor-Couette flow of a glycerol-water mixture containing a wide range of concentration (0-2000 ppm) of xanthan gum, which induces both shear-thinning and viscoelasticity, in order to assess the effect of the ... -
Taylor-Couette instability in disk suspensions: Experimental observation and theory
Gillissen, JJJ; Cagney, N; Lacassagne, T; Papadopoulou, A; Balabani, S; Wilson, HJ (2020-08-19) -
Vortex merging and splitting: A route to elastoinertial turbulence in Taylor-Couette flow
Lacassagne, T; Cagney, N; Gillissen, JJJ; Balabani, S (American Physical Society, 2020-11-23)We report experimental evidence of a new merge-split transition (MST) to elastoinertial turbulence (EIT) in Taylor-Couette flows of viscoelastic polymer solutions, caused by merging and splitting of base Taylor vortices ...
