Genetic Algorithm‐Driven Analysis of Gravitational Water Vortex Power Plant Runner Performance: A Comparative Study Integrating Experimental and Computational Fluid Dynamics

open access: yesEnergy Science &Engineering, EarlyView.
This study integrates genetic algorithm optimization, CFD simulation, and experimental validation to identify the optimal runner geometry for a gravitational water vortex turbine. The combined approach enhances vortex stability and improves energy conversion efficiency, demonstrating strong agreement between predicted and measured performance ...

Turbulence‐Intensity Effects on the Aerodynamic Performance of an H‐Type Darrieus Wind Turbine: A URANS Parametric Study

open access: yesEnergy Science &Engineering, EarlyView.
Turbulence intensity from 1% to 25% was parametrically tested on a three‐bladed H‐type Darrieus rotor across five tip speed ratios (TSRs) using two‐dimensional URANS. The optimal TSR proved the most efficient and most robust operating point simultaneously, with Cp losses capped at 5.8% even at TI = 25%. ABSTRACT The effect of inlet turbulence intensity

A Geographic Information System (GIS)–CRiteria Importance Through Intercriteria Correlation (CRITIC) Framework for Selecting Solar Photovoltaics Sites: A Case Study

open access: yesEnergy Science &Engineering, EarlyView.
A novel framework integrating environmental constraints, topography, infrastructure accessibility, and solar irradiation was developed to identify optimal utility‐scale solar photovoltaics (PV) sites in Lithuania. Western and central Lithuania showed the highest suitability for future solar PV expansion.

Convergence and Residual Error Analysis of Unsteady MHD Stagnation Flow Over a Cylindrical Surface With Streamline and Isotherm Visualization

open access: yesEnergy Science &Engineering, EarlyView.
The novelty of the current study is that the unsteady MHD Cross nanofluid model is, for the first time, coupled with the melting heat transfer at the stagnation point over a horizontally extended cylinder in a Darcy–Forchheimer porous medium. This work connects complex rheological behaviors and phase‐change phenomena in a unique way, with the only ...

Colonial and gendered peace: Decolonial perspectives on peace in Nagorno‐Karabakh

open access: yesFeminist Anthropology, EarlyView.
Abstract This article critically interrogates peace processes in the aftermath of the First Nagorno‐Karabakh War by centering the lived experiences and political voices of Armenian and Azerbaijani internally displaced and refugee women, based on ethnographic fieldwork and in‐depth interviews conducted in 2019.

“You just want to re‐open our biggest wounds, don't you?”: Homeplace ethnography as (polluted) environmental method

open access: yesFeminist Anthropology, EarlyView.
Abstract When I was 12, my family told me a story about their community falling apart and coming together, a time when someone tried putting a nuclear facility in their (our?) hometown. Since we moved when I was too young to remember, the story had little significance until I embarked on a “hometown” ethnographic journey for my dissertation.

Assemblages of care: Moral economies, classed labor, and affective exhaustion among Karachi's working middle‐class women

open access: yesFeminist Anthropology, EarlyView.
Abstract This article explores how working middle‐class women in Karachi navigate the intersecting burdens of care and self‐care within the affective, infrastructural, and ideological conditions of urban precarity. Drawing on twelve semi‐structured interviews conducted across homes, workplaces, and cafés in the city, seven of which anchor the primary ...

Programmable crack dynamics engineering enables flexible strain sensors with high linearity

open access: yesFlexMat, EarlyView.
First‐decoupling theoretical framework of crack evolution elucidating the control methods, mechanistic insights, and structure‐activity relationships is established. Crack propagation from uncontrollable randomness systematically evolves into spatially ordered states.
