The water surface response to subcritical turbulent flow over a backward-facing step (BFS) is studied via high-resolution large-eddy simulation (LES). LES method validated first using data of previously reported experiments. LES-predicted decomposed into different types gravity waves as well turbulence-driven forced waves. Analysis the reveals interplay between low-frequency large-scale turbule...

This work focuses on web dynamics and wrinkles analysis in industrial web handling systems by using finite element modeling. The main objective is to simulate wrinkles in a real environment with the control part of the system, depending on mechanical parameters and process data. The effects of misaligned rollers and a roller deflection are specifically analyzed in order to study the influence o...

Direct numerical simulations are performed to predict the three-dimensional unsteady flow interactions in the near-field of a square jet issuing normal to a cross-flow. The simulated flow features reveal the formation of an upstream horseshoe vortex system, which is the result of an interaction between the oncoming channel floor shear layer and the transverse jet; the growth of a sequence of Ke...

We investigated the role of nitric oxide (NO) in leukocyte-endothelium interaction, blood-brain barrier (BBB) function and oxygen free-radical production in the rat pial microcirculation. In a closed cranial window preparation (dura removed) over the parietal cortex of pentobarbital-anesthetized Wistar rats, NO synthase (NOS) was inhibited by systemic and/or topical application of N omega-nitro...
