Recurrent flow patterns as a basis for turbulence: predicting statistics from structures
Jacob Page, Peter Norgaard, Michael P. Brenner +1
A dynamical systems approach to turbulence envisions the flow as a trajectory through a high-dimensional state space transiently visiting the neighbourhoods of unstable simple inva…
Polymeric diffusive instability leading to elastic turbulence in plane Couette flow
Miguel Beneitez, Jacob Page, Rich R. Kerswell
Elastic turbulence is a chaotic flow state observed in dilute polymer solutions in the absence of inertia. It was discovered experimentally in circular geometries and has long been…
Wall shear stress and pressure patterns in aortic stenosis patients with and without aortic dilation captured by high-performance image-based computational fluid dynamics
Hadi Zolfaghari, Mervyn Andiapen, Andreas Baumbach +2
Spatial patterns of elevated wall shear stress and pressure due to blood flow past aortic stenosis (AS) are studied using GPU-accelerated patient-specific computational fluid dynam…
Threshold transient growth as a criterion for turbulent mean profiles
Vilda K. Markeviciute, Rich R. Kerswell
Lozano-Duran et al (J. Fluid Mech., 914, A8, 2021) have recently identified the ability of streamwise-averaged turbulent streak fields in minimal cha…
Finite-amplitude elastic waves in viscoelastic channel flow from large to zero Reynolds number
Gergely Buza, Miguel Beneitez, Jacob Page +1
Using branch continuation in the FENE-P model, we show that finite-amplitude travelling waves borne out of the recently-discovered linear instability of viscoelastic channel flow (…
Non-equivalence of quasilinear dynamical systems and their statistical closures
G. V. Nivarti, R. R. Kerswell, J. B. Marston +1
It is widely believed that statistical closure theories for dynamical systems provide statistics equivalent to those of the governing dynamical equations from which the former are…
