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…
Objective quantification of Particle Pair Diffusion in Homogeneous Isotropic Turbulence
Nadeem A. Malik, Fazle Hussain
Turbulence consists of interacting flow structures covering a wide range of length and time scales. A long-standing question looms over pair diffusion of particles in close proximi…
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…
Dynamics of fracturing saturated porous media and self-organization of rupture
C. Peruzzo, D. T. Cao, E. Milanese +4
Analytical solutions and a vast majority of numerical ones for fracture propagation in saturated porous media yield smooth behavior while experiments, field observations and a few…
Dynamics of a spatially developing liquid jet with slower coaxial gas flow
Arash Zandian, William A. Sirignano, Fazle Hussain
A three-dimensional round liquid jet within a low-speed coaxial gas flow is numerically simulated and explained via vortex dynamics ( method). The instabilities on the liquid-…
