Three-Dimensional Smoothed Particle Hydrodynamics Method for Simulating Free Surface Flows [PDF]

, 2013
In this paper, we applied an improved Smoothing Particle Hydrodynamics (SPH) method by using gradient kernel renormalization in three-dimensional cases. The purpose of gradient kernel renormalization is to improve the accuracy of numerical simulation by ...

Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

Deep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Ultra‐High Strength and Environmentally Stable Fluorinated Solid‐State Ion‐Conductive Elastomers with Folding‐Paper‐Structured Triboelectric Nanogenerators for Wave Energy Harvesting

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a polyurethane‐based fluorinated SICEs with excellent mechanical properties (7.35 MPa and 61.4 MJ m−3), conductivity (4.2 × 10−4 S cm−1), and harsh environmental resistance were prepared by a “three birds with one stone” strategy that combines multiple interactions with fluorine effects. The paper‐folding TENG is capable of harvesting not

Organic–Inorganic Composite Nanofibers Based on YSZ Nanofibers Anchored PANI/SnS2 Heterojunction for Flexible Room Temperature NO2 Sensor

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel organic–inorganic YSZ@PANI/SnS2 composite nanofiber film was prepared via an in‐situ construction strategy of a PANI interfacial layer. The biomimetic "branch‐leaf" structure effectively disperses and releases stress and energy, while accelerating gas diffusion/transport and providing abundant active sites.

Theoretical and experimental evidence of non-symmetric doubly localized rogue waves

, 2014
We present determinant expressions for vector rogue wave solutions of the Manakov system, a two-component coupled nonlinear Schr\"odinger equation. As special case, we generate a family of exact and non-symmetric rogue wave solutions of the nonlinear ...

The EU's Strategy for Sustainability: A Landmark Turn With the European Green Deal?

European Policy Analysis, EarlyView.
ABSTRACT While the European Green Deal (EGD) has been widely recognized as a milestone in the EU's sustainability strategy, scholars disagree on the nature of the policy change it represents. Critics highlight its limited social and environmental ambitions, despite its portrayal as a “man on the moon” moment.
