TESTING OF RANS TURBULENCE MODELS ON A PROBLEM OF FREE CONVECTION NEAR A SUDDENLY HEATED VERTICAL PLATE

St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2020
The results of testing of several RANS turbulence models on a problem of free convection near a suddenly heated infinite vertical plate based on comparison with classic literature data are presented.

A Review of Black Phosphorus‐Based Materials: From Preparation Strategies to Characterization Techniques

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The structure, properties, preparation methods, and characterization techniques of BP. As a typical 2D layered material, black phosphorus (BP) demonstrates exceptional promise in various fields, particularly in energy storage for alkali metal‐ion batteries. However, its distinctive structure and properties, together with the compositional complexity of

A review of turbulence measurements using ground-based wind lidars [PDF]

Atmospheric Measurement Techniques, 2013
A review of turbulence measurements using ground-based wind lidars is carried out. Works performed in the last 30 yr, i.e., from 1972–2012 are analyzed. More than 80% of the work has been carried out in the last 15 yr, i.e., from 1997–2012.

The spatio-temporal spectrum of turbulent flows

, 2015
Identification and extraction of vortical structures and of waves in a disorganised flow is a mayor challenge in the study of turbulence. We present a study of the spatio-temporal behavior of turbulent flows in the presence of different restitutive ...

Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces

Distribution of Acoustic Power Spectra for an Isolated Helicopter Fuselage

EPJ Web of Conferences, 2016
The broadband aerodynamic noise can be studied, assuming isotropic flow, turbulence and decay. Proudman’s approach allows practical calculations of noise based on CFD solutions of RANS or URANS equations at the stage of post processing and analysis of ...

Sobre la convexidad de la función de presión en el problema de la filtración no lineal

Revista de Matemática: Teoría y Aplicaciones, 2009
We prove the convexity of the pressure function v for the isotropic ideal gaz flow, based on the theorem about the zeros of the solution of the parabolic equation (1) Keywords: fluid mechanics, turbulence, parabolic ...

Climatology of upper‐tropospheric turbulence: Capabilities and limitations of aircraft reports and ERA5 reanalysis diagnostics

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Based on turbulence diagnostics, airlines are willing to avoid up to 15% of the airspace in order to avoid a fraction of turbulence that takes up about 0.1% of the airspace. This study quantifies these three fractions using turbulence reports from commercial aircraft and ERA5 reanalysis diagnostics, revealing that the low and regionally variable ...

Aligning Real‐Time Recurrence Computational Fluid Dynamics Simulations with Plant Data for the Ruhrstahl–Heraeus Degassing Process of Steel

steel research international, EarlyView.
Uncertainties exist in computational fluid dynamics (CFD) modeling of complex metallurgical processes, even when partly validated by laboratory experiments. rCFD enables computationally efficient prediction of long‐term RH degassing and can be adapted to vary flow conditions.
