Combined three-dimensional flow field measurements and motion tracking of freely moving spheres in a turbulent boundary layer

Abstract A combination of time-resolved tomographic particle image velocimetry, refractive index matching technique and machine vision algorithms was used to measure the translational and rotational

Verification of Fuel Consumption and Carbon Dioxide Emissions under Sulfur Restriction Policy during Oceanographic Navigation

The paper presents a comparison of the fuel oil (FO) consumption and carbon dioxide (CO2) emissions of a container ship’s 8000 twenty-foot equivalent unit (TEU) during oceanographic navigation. The

Particle–fluid–wall interaction of inertial spherical particles in a turbulent boundary layer

Abstract We study the dynamics of dilute, slightly negatively buoyant, millimetre-size spherical particles fully suspended in a smooth-wall open channel flow. The Reynolds number is $Re_{\tau } =



TMPRSS2-ERG gene fusion is not associated with outcome in patients treated by prostatectomy.

It is concluded that translocation of TMPRSS2-ERG is not associated with outcome, and the aggressive clinical features associated with CNI of chromosome 21 reflect generalized aneuploidy and are not due to CNI specifically of rearranged TMPR SS1-ERG.

Dynamics and wall collision of inertial particles in a solid–liquid turbulent channel flow

The dynamics and wall collision of inertial particles were investigated in non-isotropic turbulence of a horizontal liquid channel flow. The inertial particles were

This paper concerns the flow about a sphere placed in a weak shear flow of an inviscid fluid. The secondary velocity resulting from advection of vorticity by the irrotational component of the flow is

Spatially and temporally resolved measurements of bead resuspension and saltation in a turbulent water channel flow

Abstract Resuspension and saltation of nearly neutrally buoyant polystyrene beads $({d}_{p} = 583\pm 14. 4~\lrm{\ensuremath{\mu}} \mathrm{m} , {\rho }_{p} = 1050~\mathrm{kg} ~{\mathrm{m}

Measurements of the mean force on a particle near a boundary in turbulent flow

The transport of particles through gaseous systems is controlled by three factors: their arrival to the surface; whether or not they bounce upon impact; and when (if ever) they are resuspended from

Interactions of a stationary finite-sized particle with wall turbulence

Reliable information on forces on a finite-sized particle in a turbulent boundary layer is lacking, so workers continue to use standard drag and lift correlations developed for a laminar flow to

Measurement of the translation and rotation of a sphere in fluid flow

The problem of determining the translation and rotation of a spherical particle moving in fluid flow is considered. Lagrangian tracking of markers printed over the surface of a sphere is employed to

Coupling Asynchrony and Interrupts: Place Chart Nets

It is shown that PCNs are a non-trivial generalization of classical PNs, in the sense that for the finite (bounded) case modeling a PCN may require an exponentially larger PN, and for the infinite (unbounded), boundedness of PCNs is decidable.
