Deciphering the Morphological Origins of X-shaped Radio Galaxies: Numerical Modeling of Backflow versus Jet Reorientation

The Astrophysical Journal Supplement Series, 2023
X-shaped radio galaxies (XRGs) develop when certain extragalactic jets deviate from their propagation path. An asymmetric ambient medium (backflow model) or complex active galactic nucleus activity (jet-reorientation model) enforcing the jet direction to

A Multistage Venturi Amplifier for Rapid Inflation of Soft Robots

Advanced Intelligent Systems, EarlyView.
This work presents the amplifier inflator for soft robotic systems (AIRS), a compact, lightweight, and effective device for rapidly deploying inflatable structures to high pressure. By integrating a check valve with a Venturi‐based air entrainer, AIRS delivers an initial high‐flow output followed by pressurization, supporting fast inflation and ...

Local wavevector near energy backflow zones of optical vortices

Computer Optics
In this paper, we consider the behavior of the phase and local wave vector of a tightly focused optical vortex with linear polarization. It is shown that the regions of phase singularity correspond to giant values of the local wave vector. In contrast to the scalar approximation, when the theory predicts that when focusing an optical vortex with a ...

Hybrid Inertial–Centrifugal Gas–Liquid Separator: CFD‐Driven Optimization Using Coupled Discrete Phase and Wall‐Film Modeling With Response Surface Methodology

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Efficient removal of liquid aerosols from compressed gas streams is essential in chemical and energy processes. Conventional separators relying on a single mechanism (inertial or centrifugal) struggle to capture both fine and coarse droplets simultaneously.

Multiscale Modeling Approach of Slot Die Coating of Unidirectional Glass Fiber Fabric

Journal of Applied Polymer Science, EarlyView.
2D macroscale and microscale computational fluid dynamic (CFD) models are combined in a multiscale approach to develop a model for slot die coating of glass fiber (GF) fabrics in cellulose nanocrystal (CNC) dispersion as a sizing. For slot die coating models with and without vacuum assist, the model is able to predict stable operating parameters which ...

A Boost CLLC Converter Controlled by PWM and PFM Hybrid Modulation for Photovoltaic Power Generation

IEEE Access, 2020
When an input terminal is connected to a solar panel with a low voltage level and large power range fluctuation, a Boost type CLLC converter controlled by fixed frequency pulse width modulation (PWM) reduces the utilization of PV electric energy, and the

A narrow bandgap Schottky heterojunction Fe2N/CeO2 microneedle triggering sonodynamic reactive oxygen species storm for drug‐resistance‐free skin fungal infection

BMEMat, EarlyView.
Inorganic sonosensitizers suffer from inefficient electron‐hole separation, rapid recombination, and wide bandgaps in anti‐fungal applications. We propose MN@Fe2N/CeO2 to directly eliminate fungi without drug resistance. Combining semiconductor CeO2's advantages with Fe2N's high work function and activity enables efficient Schottky heterojunctions ...
