Low Reynolds number airfoils

, 2018
У овој тези је моделирано струјање око аеропрофила са ниским Рејнолдсовим бројем. Вискозно невискозна интеракција комбинована са моделирањем ламинарног мехура је ефикасан метод за конструисање нових аеропрофила систематским модификовањем облика аеропрофила. Невискозно решење је засновано на конформном пресликавању.

The Synergy of Green HRM and a Proactive Environmental Strategy in Cultivating Environmental and Financial Performance Through Green Innovation

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines how green human resource management (HRM) contributes to environmental and financial performance via green innovation. We develop and test a moderated mediation model in which green product and green process innovation act as parallel mediating mechanisms, while proactive environmental strategy moderates their effectiveness.

Beauty With a Conscience: The Power of CSR Communication Dimensions in the Formation of Purchase Intention Among Cosmetics Consumers

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Cosmetics production and consumption, which have been growing steadily in recent years, are associated with a number of negative environmental, moral, and health impacts. This study examines the influence of cosmetics producers' corporate social responsibility (CSR) communication on the formation of purchase intention among Czech consumers ...

Photothermal bubble: Dynamics, manipulation, and applications

Droplet, EarlyView.
As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.

Localized 3D acoustic streaming in microdroplets using high‐frequency micro‐beam IDTs

Droplet, EarlyView.
Miniaturized 160 MHz acoustic microbeam transducers, with a size much smaller than droplets, enable precise localized actuation, generating complex three‐dimensional streaming and tunable particle aggregation. This concept provides high‐resolution, non‐contact fluid manipulation for biosensing, lab‐on‐chip diagnostics, and targeted drug screening ...

Large droplet release

Droplet, EarlyView.
Curved hydrophobic mesh surfaces enable stable release of large droplets exceeding the capillary length. By tuning surface curvature, porosity, and acceleration, oscillatory breakup is suppressed, producing near‐spherical droplets ideal for high‐precision fluid applications and multiphase flow control.

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).

Modeling proppant transport and settling in a 3D propagating fracture

Deep Underground Science and Engineering, EarlyView.
A versatile multiphysics tool is presented for simulating the complex processes involved in hydraulic fracturing treatments. The model couples fracture opening and propagation, variable‐density slurry flow, and proppant particle transport within the multiphysics object‐oriented simulation environment framework, based on two‐phase mixture equations and ...

Modeling and monitoring injectivity evolution during cold CO2 injection with field evidence from aquistore carbon capture and storage operations

Deep Underground Science and Engineering, EarlyView.
This work integrates 5 years of field data from the Aquistore CCS project with a non‐isothermal THM modeling framework to explain how cold CO2 injection alters injectivity over time. The study shows that sustained cooling near the wellbore reduces effective stresses, promotes tensile micro‑cracking, and leads to semi‑reversible permeability enhancement

Reusing depleted oil and gas wells for geothermal energy: Feasibility, challenges, and a decision‐making framework for sustainable conversion

Deep Underground Science and Engineering, EarlyView.
The graphical abstract presents a structured decision‐support framework for assessing the feasibility of converting depleted oil and gas wells into geothermal energy systems. The left panel illustrates a comprehensive, multi‐stage decision‐making framework progressing from prefeasibility screening and technical–economic analysis to policy alignment ...
