The traditional approach for the hydrodynamic characterization of the flow down stepped spillways is through physical modeling, which is susceptible to scale effects and has limitations related to experimental apparatus, laboratory space and the spat

On the evaluation of bridge deck flutter derivatives using RANS turbulence models
Autor: Francesco Ubertini, F. Brusiani, Luca Patruno, P. Vaona, S. de Miranda
Publikováno v: Journal of Wind Engineering and Industrial Aerodynamics. 119:39-47
This paper concerns the capabilities and the limitations of computational fluid dynamic simulations in evaluating the dynamic aeroelastic coefficients currently used to study the bridge deck instability due to wind loading. The attention is focused o

Matematično in fizično modeliranje toka v rekah s poplavnimi področji
Autor: Bombač, Martin
V doktorski disertaciji so obravnavani različni pristopi k modeliranju toka v rekah s poplavnimi področji. Podatki, pridobljeni z meritvami na fizičnem hidravličnem modelu območja reke Save z izrazitimi poplavnimi področji, so služili za podro

Speeds of discontinuity waves in turbulent superfluids
Autor: ARDIZZONE, Lucia
In this work, using a hydrodynamical model previously formulated, the possible modes of propagation of discontinuity waves in turbulent superfluids are studied in the nonlinear regimes. The field equations are written down, then the wave speeds are d

Numerical analysis of wind-induced vibration on 2D bluff bodies by using the k-omega turbulence model
Autor: BRUSIANI, FEDERICO, CAZZOLI, GIULIO, DE MIRANDA, STEFANO, UBERTINI, FRANCESCO, P. Vaona
This paper concerns the influence of turbulence model adopted to numerically predict the aero-elastic phenomena in Fluid Structure Interaction (FSI) problems. After a detailed evaluation of the main suitable turbulence models available in Reynolds Av

Journal of Fluid Mechanics, 646, 527-536. Cambridge University Press
The statistics of velocity differences between pairs of heavy inertial point particles suspended in an incompressible turbulent flow is studied and found to be extremely intermittent. The problem is particularly relevant to the estimation of the effi

Prognostic value of heart rate turbulence and its relation to inflammation in patients with unstable angina pectoris
Autor: Sergio Valsecchi, Antonio Giuseppe Rebuzzi, Attilio Maseri, Domenico Cianflone, Gregory A. Sgueglia, Gaetano Antonio Lanza, Filippo Crea, Alfonso Sestito, Giulia Angeloni
Heart rate turbulence (HRT) provided insights into cardiac autonomic function and predicted clinical outcome in patients with myocardial infarction. A relation between cardiac autonomic function and inflammation was shown in several clinical settings
