Controlling heat transport and flow structures in thermal turbulence using ratchet surfaces
Hechuan Jiang, Xiaojue Zhu, Varghese Mathai +3
In this combined experimental and numerical study on thermally driven turbulence in a rectangular cell, the global heat transport and the coherent flow structures are controlled wi…
Two-Scalar Turbulent Rayleigh-Benard Convection: Numerical Simulations and Unifying Theory
Yantao Yang, Roberto Verzicco, Detlef Lohse
We conduct direct numerical simulations for turbulent Rayleigh-Bénard (RB) convection, driven simultaneously by two scalar components (say, temperature and salt concentration) with…
Statistics of turbulence in the energy-containing range of Taylor-Couette compared to canonical wall-bounded flows
Dominik Krug, Xiang I. A. Yang, Charitha M. de Silva +4
Considering structure functions of the streamwise velocity component in a framework akin to the extended self-similarity hypothesis (ESS), de Silva \textit{et al.} (\textit{J. Flui…
Deformable ellipsoidal bubbles in Taylor-Couette flow with enhanced Euler-Lagrange tracking
Vamsi Spandan, Roberto Verzicco, Detlef Lohse
In this work we present numerical simulations of sub-Kolmogorov deformable bubbles dispersed in Taylor-Couette flow (a wall-bounded shear system) with rotating inner cylinde…
AFiD-GPU: a versatile Navier-Stokes Solver for Wall-Bounded Turbulent Flows on GPU Clusters
Xiaojue Zhu, Everett Phillips, Vamsi Spandan +9
The AFiD code, an open source solver for the incompressible Navier-Stokes equations ({\color{blue}\burl{http://www.afid.eu}}), has been ported to GPU clusters to tackle large-scale…
Roughness-facilitated local 1/2 scaling does not imply the onset of the ultimate regime of thermal convection
Xiaojue Zhu, Richard J. A. M. Stevens, Roberto Verzicco +1
In thermal convection, roughness is often used as a means to enhance heat transport, expressed in Nusselt number. Yet there is no consensus on whether the Nusselt vs. Rayleigh numb…
