The purpose of the present work is to study the effect of an isolated depression and a related rocky outcrop on the flow field in a mesotidal channel of the Bahía Blanca Estuary, Argentina. To this end, measurements of ...

We present a novel approach for tailoring the laser induced surface topography upon femtosecond (fs) pulsed laser irradiation. The method employs spatially controlled double fs laser pulses to actively regulate the hydro...

We develop an age-structured hydrodynamic (HD) theory that describes the collective behavior of N≫1 anomalously diffusing particles under stochastic renewal resetting. The theory treats the age of a particle—the time...

Widespread attention has been drawn to the underwater biomimetic robotic fish due to its excellent agility and little environmental disturbance. A hybrid-driven bionic robotic fish outfitted with dual-propeller thrusters...

A new hydrodynamic code applicable to a space of an arbitrary number of dimensions is discussed and applied to a variety of polytropic stellar models. The principal feature of the method is the use of statistical techniq...

Plasmonic phenomena in metals are commonly explored within the framework of classical electrodynamics and semiclassical models for the interactions of light with free-electron matter. The more detailed understanding of m...

River confluences are notable features in the drainage system with complex hydrodynamics, bed morphology, sediment transport, and mixing processes. Junction planform plays a pivotal role in the confluence hydrodynamics. ...

The goal of this study is to evaluate the influence of tributary flow density differences on hydrodynamics and mixing at a confluent meander bend. A detailed field characterization is performed using an Acoustic Doppler ...

We implement a simple hydrodynamical model to study the behavioural swimming tilt angle of open swimbladder fish. For this purpose we analysed the force stability which act upon a fish swimming horizontally at a constant...

The Bahía Blanca Estuary is a complex system of channels and tidal flats where the most important deep water harbour system of Argentina is located. The main goal of the present work was to obtain a hydrodynamic conce...

We propose an original concept for on-chip excitation and amplification of surface plasmon polaritons. Our approach, named nanoresotron, utilizes the collective effect of dissipative instability of a 2D direct current fl...

This paper presents a two-way coupling methodology between the robust Smoothed Particle Hydrodynamics (SPH)-based fluid solver DualSPHysics and the lumped-mass mooring dynamics solver MoorDynPlus. Such integration enable...

X-ray absorption spectroscopy (XAS) can probe the local structure of very diluted and dispersed species, as occurs for active ones in catalysts. These studies can be performed even during catalytic reactions, by using in...

Abstract The aim of this paper is to study the effect of agitator’s types on the turbulent flows in stirred tanks without and with baffles. The hydrodynamics behavior induced by four different agitator’s types: a Rus...

We present a quantitative analysis of the properties of galaxies and structures evolving in universes dominated by different modified gravitational models, including two variants of the f(R)-gravity (F) and two of the Dv...

Designing floating wind turbine systems requires integrated load assessments (ILA) using fully coupled hydro-servo-aero-elastic models. In most cases, floater hydrodynamics are represented using potential-flow models for...

The origin of R Coronae Borealis stars has been elusive for over 200 years. Currently, two theories for their formation have been presented. These are the final flash scenario, in which a dying asymptotic giant branch st...

Runoff, groundwater recharge and discharge, and surface water-groundwater interaction are the main driving forces of wetlands. The quantification of such flows is crucial information in the restoration and management of ...

Context. Astronomical environments are governed by a complex interplay of physical processes, including gravitational dynamics, radiative transfer, stellar evolution, chemistry, and hydrodynamics. These processes span a ...

By means of zoom-in hydrodynamic simulations, we quantify the amount of neutral hydrogen (H i) hosted by groups and clusters of galaxies. Our simulations, which are based on an improved formulation of smoothed particle h...

Abstract Accurate quantification of external force is the key to improve the high-precision hemming of autobody closure panels. However, the mechanism of external force on forming quality of complex contour sheet metal w...

Observations of molecular structures on scales of ∼0.1−50 pc show that the specific angular momentum ( j ) scales with radius ( R ) as j  ∼  R ^3/2 . We study the effects of turbulence, gravity, and the magnetic ...

This study deals with the roles of a magnetic field and circular rotation of a circular cylinder on the dissemination of solid phase within a nanofluid-filled square cavity. Two wavy layers of the non-Darcy porous media ...
