Decay of Swirling Turbulent Flow in Rod-bundle

open access: yesJournal of Fluid Science and Technology, 2006
An LES was carried out to clarify the mechanism of decaying swirl in a rod-bundle. In our LES, an immersed boundary method was used to treat this complex wall boundary in the Cartesian grid system. A consistent immersed boundary method and a one-equation

Size‐Dependent Characteristics of Surface‐Rooted Three‐Dimensional Convective Objects in Continental Shallow Cumulus Simulations

open access: yesJournal of Advances in Modeling Earth Systems, Volume 14, Issue 3, March 2022., 2022
Abstract A segmentation algorithm is applied to high resolution simulations of shallow continental convection to identify individual convective 3D objects within the convective boundary layer, in order to investigate which properties of the objects vary with the object width.

Le fou, le solipsiste et le philosophe [PDF]

open access: yesPhilonsorbonne, 2020
On trouve parfois, chez Wittgenstein, la figure du fou associee a celle du philosophe. Mais il s’agit alors generalement du philosophe au sens pejoratif du terme. C’est-a-dire au sens de celui qui profere des non-sens, qui emploie des expressions decrochees de tout usage, sans se donner les moyens de leur conferer un sens.

Simulation of Ternary Mixing in a Coannular Jet-in-Crossflow

open access: yesJournal of Fluid Science and Technology, 2009
A method for LES of ternary mixing in turbulent flows is presented and partly validated against DNS data. The subgrid-scale mixing state is characterized by joint presumed discrete distributions, i.e.

Prostoupení kulturní krajiny a lesa v kontextu kulturní ekologie

open access: yesEnvigogika, 2014
Kulturní krajina a její aspekty jsou dnes frekventovaná témata kulturní a krajinné ekologie. Svět významů kulturní krajiny k sobě logicky přitahuje i svůj protipól v podobě divočiny a přírody pro své doplnění a vymezení. Pojmy divočina a příroda je třeba

Study of the influence of turbulent flows on the aerodynamic performance of fixed-wing aircraft type UAV MALE [PDF]

open access: yesINCAS Bulletin, 2023
A study of the air behavior in the near-wake region of the NACA0012 airfoil infinite wing model at low Reynolds numbers was conducted. The study consisted of comparing the results obtained from experiments with those from numerical simulations.
