Rigorous ultimate scaling in rapidly rotating steady convection
Gabriel Hadjerci, Shingo Motoki, Genta Kawahara
Rapidly rotating Rayleigh-Bénard convection admits a class of exact steady single-mode solutions describing high-amplitude convection cells. Using a matched asymptotic analysis in…
Passive scalar cascade in the intermediate layer of turbulent channel flow for
Emanuele Gallorini, Shingo Motoki, Genta Kawahara +1
Similarities and differences between Kolmogorov scale-by-scale equilibria/non-equilibria for velocity and scalar fields are investigated in the intermediate layer of a fully develo…
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…
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…
Optimal heat transfer enhancement in plane Couette flow
Shingo Motoki, Genta Kawahara, Masaki Shimizu
We discuss what is an optimal velocity field for more heat transfer and less energy dissipation under the constraints of the continuity equation for the velocity and the advection-…
