Attached flow structure and streamwise energy spectra in a turbulent boundary layer

Mon, 05/14/2018 - 11:00

Author(s): S. Srinath, J. C. Vassilicos, C. Cuvier, J.-P. Laval, M. Stanislas, and J.-M. Foucaut

On the basis of (i) particle image velocimetry data of a turbulent boundary layer with large field of view and good spatial resolution and (ii) a mathematical relation between the energy spectrum and specifically modeled flow structures, we show that the scalings of the streamwise energy spectrum E1...

Validation of model predictions of pore-scale fluid distributions during two-phase flow

Mon, 05/14/2018 - 11:00

Author(s): Tom Bultreys, Qingyang Lin, Ying Gao, Ali Q. Raeini, Ahmed AlRatrout, Branko Bijeljic, and Martin J. Blunt

Pore-scale two-phase flow modeling is an important technology to study a rock's relative permeability behavior. To investigate if these models are predictive, the calculated pore-scale fluid distributions which determine the relative permeability need to be validated. In this work, we introduce a me...

Experimental study on the evolution of Peregrine breather with uniform-depth adverse currents

Mon, 05/07/2018 - 11:00

Author(s): B. Liao, Y. Ma, X. Ma, and G. Dong

A series of laboratory experiments were performed to study the evolution of Peregrine breather (PB) in a wave flume in finite depth, and wave trains were initially generated in a region of quiescent water and then propagated into an adverse current region for which the current velocity strength grad...

Dissipation, intermittency, and singularities in incompressible turbulent flows

Thu, 05/03/2018 - 11:00

Author(s): P. Debue, V. Shukla, D. Kuzzay, D. Faranda, E.-W. Saw, F. Daviaud, and B. Dubrulle

We examine the connection between the singularities or quasisingularities in the solutions of the incompressible Navier-Stokes equation (INSE) and the local energy transfer and dissipation, in order to explore in detail how the former contributes to the phenomenon of intermittency. We do so by analy...

Shock-wave structure based on the Navier-Stokes-Fourier equations

Mon, 04/30/2018 - 11:00

Author(s): F. J. Uribe and R. M. Velasco

We use the Navier-Stokes-Fourier constitutive equations to study plane shock waves in dilute gases. It is shown that the experimental information on the normalized density profiles can be fit by using the so-called soft sphere model, in which the viscosity and thermal conductivity are proportional t...
