Abstract The occurrence of data outliers in PIV measurements remains nowadays a problematic issue; their effective detection is relevant to the reliability experiments. This study proposes novel approach from time-averaged three-dimensional data. principle based on agreement measured turbulent kinetic energy (TKE) transport equation. ratio between local advection and production terms TKE along ...

Aquatic vegetation appears very often in rivers and floodplains, which significantly affects the flow structure. In this study, experiments have been conducted to investigate effects of submerged arrangement patterns density on Deflected non-bending is arranged square staggered configurations channel bed a large-scale flume. Results showed that configuration leads intensified streamwise velocit...

Turbulence kinetic energy (TKE) schemes are routinely used for turbulence parameterization in numerical weather prediction models. A key component of these is the so-called length scale. Novel scale-aware, budget-based diagnostics that account cross-scale transfer variances to evaluate performance selected scale formulations gray zone turbulence. The computed using coarse-graining method on hig...

The key role in the calculation of post-neutron fragment yields (independent FPY) is played by pre-neutron distributions Y(A,TKE) and prompt neutron multiplicity (calculated frame a emission model). knowledge excitation energies fully accelerated fragments crucial any model. So that influence on independent FPY two methods total energy (TXE) partition, one based modeling at scission another par...

The lattice Boltzmann method is employed to conduct direct numerical simulations of turbulent open channel flows with the presence finite-size spherical sediment particles. uniform particles have a diameter approximately 18 wall units and density ?p=2.65?f, where ?p ?f are particle fluid densities, respectively. Three low volume fractions ?=0.11%, 0.22%, 0.44% used investigate particle-turbulen...

Wind gusts (gusts) are sudden increases in wind speed that potentially cause severe damage to infrastructure. Gusts occur within several seconds but numerical weather models typically predict future with a time step of tens or minutes. Therefore, parameterization is needed estimate gust. can be produced convectively and non-convectively depending on the presense thunderstorm. The gust schemes m...

Wave impacts on vertical caissons may cause breakwaters failures. This paper focuses the analysis of stability under violent wave by using a triple-coupled Fluid-Porous-Solid model. The fluid model is described Volume-Averaged Reynolds-Averaged Navier-Stokes equations in which nonlinear Forchheimer for porous medium are added to inertia terms. solid model, based DDA method an implicit DEM metho...

In this article, the optimization of a twisted strip heat exchanger was explored aiming at enhancing transfer. To end, governing equations using ANSYS-FLUENT software and nanofluid flow k-ε RNG turbulence model were simulated in exchanger, respectively. The investigated parameters included temperature, pressure, velocity, kinetic energy (TKE), concentration, shape factor, Reynolds number, diame...

Absrfucr-Given two discrete memoryless channels @MC’s) with a common input, it is desired to transmit private messagea to receiver 1 at r&R, andcommon meswgea to both receivers at rate R,, while keeping receiver 2 as ignorant of tbe private messages as possible. Measurhg ignorance by equivocation, a single-letter characterization is given of the. achievable trfplea (RI&R,-,) where 4 is the equi...
