The total kinetic energy (TKE) of fission fragments for some heavy actinides is investigated and calculated using the scission point model. First, deformation parameters are obtained by fitting results to available experimental data. Then, behavior TKE distribution fission. This indicates that Usang model can better explaine heavier than californium Unik Also, value be approximated sum Coulomb ...

The Large Eddy Simulation (LES) technique with the Smagorinsky-Lilly dynamic subgrid model and two-equation Standard k-ω Transitional turbulence model are applied to investigate non-spiral and spiral blood flow through three dimensional models of arterial stenosis and aneurysm. A spiral pattern of blood flow is thought to have many beneficial effects on hemodynamics. Previous computational stud...

In the stepped spillway, steps, by providing an artificial roughening bed, dissipate flow of energy more than other types spillways, so construction costs for stilling basin are reduced. However, what is important in this type spillway increasing effectiveness steps rate dissipation. The present study deals with experimental and numerical simulations regarding influence geometric appendance ele...

The goal of this work is to compare the main air turbulence characteristics two common areas in Amazonian landscape: a dense forest (rough surface) and water surface (smooth surface). Using wind components data collected at high frequency by sonic anemometers located just above these surfaces, intensity power spectra, temporal length scales eddies, as well terms TKE budget (TKE = turbulent kine...

Abstract Flow in rivers and the coastal ocean is controlled by frictional force exerted on water riverbed or seabed roughness. The typically characterized a drag coefficient C d , which estimated from bulk measurements often assumed constant. Here, we demonstrate relationship between bed roughness surface turbulence that can be used to make remote estimates of . We observe regions with larger r...

A model is developed to calculate the total kinetic energy (TKE) distribution of fission fragments in framework time-dependent generator coordinate method (TDGCM), extended include dissipation effects description induced dynamics. Starting from an expression for dissipative term GCM Hamiltonian that determines time evolution a statistical collective wave function, derived first part this work, ...

A principal technical objective is to simulate and understand the behavior of Lagrangian drifters and floats in the presence of deep convection in the Labrador Sea. The corollary scientific objective for the Labrador Sea DeepConvection ARI is to understand the production, transport and dissipation of TKE and scalar variances (potential temperature and salinity); and the production and transport...

To develop an accurate, compact and sensitive optical sensor capable of performing non-invasive instantaneous measurements of the rate of dissipation of turbulent kinetic energy TKE (E [m2/s3]). Turbulence dissipation rates provide vital information to determine mixing processes in the water column. In addition, enables the scaling information needed to link large mixing events with smallscale ...

Prompt publication of brief reports of important discoveries in physics may be secured by addressing them to this department. Closing dates for this department are, for the first issue of the month, tke eighteenth of the preceding month, for the second issue, the tkird of the month. Because of the late closing dates for the section no proof can be shown to authors. The Board of Editors does not...
