Local and global bifurcations to large-scale oblique patterns in inclined layer convection
Zheng Zheng, Sajjad Azimi, Florian Reetz +1
In the inclined layer convection system, thermal convection in a Rayleigh--Bénard cell tilted against gravity, the flow is subject to competing buoyancy and shear forces. For varyi…
Adjoint-based variational method for constructing periodic orbits of high-dimensional chaotic systems
Sajjad Azimi, Omid Ashtari, Tobias M. Schneider
Chaotic dynamics in systems ranging from low-dimensional nonlinear differential equations to high-dimensional spatio-temporal systems including fluid turbulence is supported by non…
Self-sustained large-scale motions in the asymptotic suction boundary layer
Sajjad Azimi, Carlo Cossu, Tobias M. Schneider
Large-scale motions, also known as superstructures, are dynamically relevant coherent structures in a wall-bounded turbulent flow, that span the entire domain in wall-normal direct…
Modified snaking in plane Couette flow with wall-normal suction
Sajjad Azimi, Tobias M. Schneider
A specific family of spanwise-localised invariant solutions of plane Couette flow exhibits homoclinic snaking, a process by which spatially localised invariant solutions of a nonli…
Self-similar invariant solution in the near-wall region of a turbulent boundary layer at asymptotically high Reynolds numbers
Sajjad Azimi, Tobias M. Schneider
At sufficiently high Reynolds numbers, shear-flow turbulence close to a wall acquires universal properties. When length and velocity are rescaled by appropriate characteristic scal…
