Boundary sources of velocity gradient tensor and its invariants
Tao Chen, Jie-Zhi Wu, Tianshu Liu +1
The present work elucidates the boundary behaviors of the velocity gradient tensor () and its principal invariants () for compressible flow in…
Strong Scaling of OpenACC enabled Nek5000 on several GPU based HPC systems
Jonathan Vincent, Jing Gong, Martin Karp +11
We present new results on the strong parallel scaling for the OpenACC-accelerated implementation of the high-order spectral element fluid dynamics solver Nek5000. The test case con…
Composite active drag control in turbulent channel flows
Jie Yao, Xi Chen, Fazle Hussain
A composite drag control (CDC) combining the opposition (OC) and spanwise opposed wall-jet forcing (SOJF) methods is studied in a turbulent channel flow via direct numerical simula…
Separation scaling for viscous vortex reconnection
Jie Yao, Fazle Hussain
Reconnection plays a significant role in the dynamics of plasmas, polymers and macromolecules, as well as in numerous laminar and turbulent flow phenomena in both classical and qua…
Statistical mechanics of a nonequilibrium steady-state classical particle system driven by a constant external force
Jie Yao, Yanting Wang
A classical particle system coupled with a thermostat driven by an external constant force reaches its steady state when the ensemble-averaged drift velocity does not vary with tim…
Point Transformations and the Relationships Among Anomalous Diffusion, Normal Diffusion and the Central Limit Theorem
Donald J. Kouri, Nikhil N. Pandya, Cameron L. Williams +2
We present new connections among anomalous diffusion (AD), normal diffusion (ND) and the Central Limit Theorem. This is done by defining a point transformation to a new position va…
Generalized Fourier transform method for nonlinear anomalous diffusion equation
Jie Yao, Cameron L. Williams, Fazle Hussain +1
The solution of a nonlinear diffusion equation is numerically investigated using the generalized Fourier transform method. This equation includes fractal dimensions and power-law d…
