Chaotic and time-periodic edge states in square duct flow
Markus Scherer, Markus Uhlmann, Genta Kawahara
We analyse the dynamics within the stability boundary between laminar and turbulent square duct flow with the aid of an edge-tracking algorithm. As for the circular pipe, the edge…
Bifurcation structure of unstable periodic orbits in plane Couette flow with the Smagorinsky model
Eiichi Sasaki, Genta Kawahara, Javier Jiménez
In order to obtain insights into dynamics of developed plane Couette turbulence, this paper considers bifurcation structure of unstable periodic orbits (UPOs) in the large-eddy-sim…
The ultimate state of turbulent permeable-channel flow
Shingo Motoki, Kentaro Tsugawa, Masaki Shimizu +1
Direct numerical simulations have been performed for heat and momentum transfer in internally heated turbulent shear flow with constant bulk mean velocity and temperature, …
Ultimate heat transfer in `wall-bounded' convective turbulence
Koki Kawano, Shingo Motoki, Masaki Shimizu +1
Direct numerical simulations have been performed for turbulent thermal convection between horizontal no-slip, permeable walls with a distance and a constant temperature differe…
Multi-scale steady solution for Rayleigh-Bénard convection
Shingo Motoki, Genta Kawahara, Masaki Shimizu
We have found a multi-scale steady solution of the Boussinesq equations for Rayleigh-Bénard convection in a three-dimensional periodic domain between horizontal plates with a const…
Can preferential concentration of finite-size particles in plane Couette turbulence be reproduced with the aid of equilibrium solutions?
Tiago Pestana, Markus Uhlmann, Genta Kawahara
This work employs for the first time invariant solutions of the Navier-Stokes equations to study the interaction between finite-size particles and near-wall coherent structures. We…
