Time-periodic inertial range dynamics
Lennaert van Veen, Alberto Vela-Martin, Genta Kawahara
We present an unstable periodic orbit in large eddy simulation of an incompressible fluid in a periodic box subject to a constant body force. The width of the inertial range of spa…
Periodic motion representing isotropic turbulence
Lennaert van Veen, Shigeo Kida, Genta Kawahara
Temporally periodic solutions are extracted numerically from forced box turbulence with high symmetry. Since they are unstable to small perturbations, they are not found by forward…
Data-driven low-dimensional model for the onset of turbulence in plane Couette flow
Masaki Shimizu, Genta Kawahara, Julius Rhoan T. Lustro
We construct low-dimensional dynamical systems for low-Reynolds-number turbulence in plane Couette flow using Kernel Quantile Regression. Exploiting the finite-dimensional structur…
Periodic orbits in Large Eddy Simulation of Box Turbulence
Lennaert van Veen, Alberto Vela Martin, Genta Kawahara +1
We describe and compare two time-periodic flows embedded in Large Eddy Simulation (LES) of turbulence in a three-dimensional, periodic domain subject to constant external forcing.…
Maximal heat transfer between two parallel plates
Shingo Motoki, Genta Kawahara, Masaki Shimizu
The divergence-free time-independent velocity vector field has been determined so as to maximise heat transfer between two parallel plates of a constant temperature difference unde…
