Spectral analysis on transport budgets of turbulent heat fluxes in plane Couette turbulence
Takuya Kawata, Takahiro Tsukahara
In recent years, scale-by-scale energy transport in wall turbulence has been intensively studied, and the complex spatial and interscale transfer of turbulent energy has been inves…
Scale interactions in turbulent plane Couette flows in minimal domains
Takuya Kawata, Takahiro Tsukahara
Interscale energy transfer in wall turbulence has been intensively studied in recent years, and both the forward (i.e. from larger to smaller scales) and reversed transfers of turb…
Viscoelasticity-induced pulsatile motion of 2D roll cell in laminar wall-bounded shear flow
Tomohiro Nimura, Takuya Kawata, Takahiro Tsukahara
For the clarification of the routes to elasto-inertial turbulence (EIT), it is essential to understand how viscoelasticity modulates coherent flow structures including the longitud…
Viscoelastic effect on steady wavy roll cells in wall-bounded shear flow
Tomohiro Nimura, Takuya Kawata, Takahiro Tsukahara
An alternative step in understanding the flows of near wall drag-reducing turbulence can be examining the flow in a well-organized streamwise vortex with a laminar background. Here…
DNS of Taylor-Couette flow between counter-rotating cylinders at small radius ratio
Ryo Tanaka, Takuya Kawata, Takahiro Tsukahara
A counter-rotating Taylor-Couette flow with relatively small radius ratios of = 0.2--0.5 was investigated over a wide range of the Reynolds number, from laminar to turbulent re…
