Destabilizing turbulence in pipe flow
J. Kühnen, B. Song, D. Scarselli +5
Turbulence is the major cause of friction losses in transport processes and it is responsible for a drastic drag increase in flows over bounding surfaces. While much effort is inve…
Conditional statistics of supersonic turbulent boundary layer in the intermittent region
Xiaoshuai Wu, Jianhan Liang, Yuxin Zhao +1
The turbulence statistics of the intermittent region in a supersonic turbulent boundary layer are studied by direct numerical simulation. Recently, Kwon et al. (2016) have shown th…
Dynamo Action in a Quasi-Keplerian Taylor-Couette Flow
Anna Guseva, Rainer Hollerbach, Ashley P. Willis +1
We numerically compute the flow of an electrically conducting fluid in a Taylor-Couette geometry where the rotation rates of the inner and outer cylinders satisfy $Ω_o/Ω_i=(r_o/r_i…
Quasi-two-dimensional nonlinear evolution of helical magnetorotational instability in a magnetized Taylor-Couette flow
G. Mamatsashvili, F. Stefani, A. Guseva +1
Magnetorotational instability (MRI) is one of the fundamental processes in astrophysics, driving angular momentum transport and mass accretion in a wide variety of cosmic objects.…
Transport properties of the Azimuthal Magnetorotational Instability
Anna Guseva, Ashley P. Willis, Rainer Hollerbach +1
The magnetorotational instability (MRI) is thought to be a powerful source of turbulence in Keplerian accretion disks. Motivated by recent laboratory experiments, we study the MRI…
Hydrodynamic turbulence in quasi-Keplerian rotating flows
Liang Shi, Bjoern Hof, Markus Rampp +1
We report a direct-numerical-simulation study of Taylor-Couette flow in the quasi-Keplerian regime at shear Reynolds numbers up to . Quasi-Keplerian rotating flo…
Analysis and modeling of localized invariant solutions in pipe flow
Paul Ritter, Stefan Zammert, Bruno Eckhardt +1
Turbulent spots surrounded by laminar flow are a landmark of transitional shear flows, but the dependence of their kinematic properties on spatial structure is poorly understood. W…
