Superposition of system response in modulated turbulent plane Couette flow
Wasy Akhtar, Rodolfo Ostilla-Monico
Traditionally, the response of a turbulent flow to modulated perturbations is expected to be complex. We conduct direct numerical simulations of turbulent Plane Couette flow, the s…
Direct numerical simulations of a cylinder cutting a vortex
Steven Soriano, Rodolfo Ostilla-Monico
The interaction between a vortex and an impacting body which is oriented normally to it is complex due to the interaction of inviscid and viscous three-dimensional mechanisms. To m…
The effect of velocity boundary conditions on the heat transfer and flow topology in two-dimensional Rayleigh-Bénard convection
Erwin P. van der Poel, Rodolfo Ostilla Mónico, Roberto Verzicco +1
The effect of various velocity boundary condition is studied in two-dimensional Rayleigh-Bénard convection. Combinations of no-slip, stress-free and periodic boundary conditions ar…
A pencil distributed finite difference code for strongly turbulent wall-bounded flows
Erwin P. van der Poel, Rodolfo Ostilla Mónico, John Donners +1
We present a numerical scheme geared for high performance computation of wall-bounded turbulent flows. The number of all-to-all communications is decreased to only six instances by…
