On the Markovian assumption in near-wall turbulence: The case of particle resuspension
David Ben-Shlomo, Ronen Berkovich, Eyal Fattal
We investigate the validity of the Markovian assumption in modeling near-wall turbulence by analyzing the detachment of micron-sized particles from the viscous sublayer. By couplin…
Adaptive degenerate space method for source term estimation using a backward Lagrangian stochastic model
Omri Buchman, Eyal Fattal
The general problem of characterizing gas source parameters based on concentration measurements is known to be a difficult task. As many inverse problems, one of the main obstacles…
Turbulence -- Obstacle Interactions in the Lagrangian Framework: Applications for Stochastic Modeling in Canopy Flows
Ron Shnapp, Yardena Bohbot-Raviv, Alex Liberzon +1
Lagrangian stochastic models are widely used to predict and analyze turbulent dispersion in complex environments, such as in various terrestrial and marine canopy flows. However, d…
Extended 3D-PTV for direct measurements of Lagrangian statistics of canopy turbulence in a wind tunnel
Ron Shnapp, Erez Shapira, David Peri +3
Direct estimation of Lagrangian turbulence statistics is essential for the proper modeling of dispersion and transport in highly obstructed canopy flows. However, Lagrangian flow m…
Deuterium-deuterium nuclear cross-sections in insulator and metallic environments
David Salzmann, Michael Hass
The three-dimensional Thomas-Fermi (TF) model is used to simulate the variation of the d+d to t + p cross-section at low impact energies, when the target deuterium nucleus is embed…
Spectroscopy Of Low Metallicity Giant H II Regions: A grid of low Metallicity Stellar atmospheres
S. L. Pistinner, P. H. Hauschildt, D. Eichler +1
We calculate a grid of spherically symmetric OB stellar atmospheres at low metallicities, including both non-local thermodynamic equilibrium (NLTE) and metal line blanketing effect…
