Process‐informed co‐optimization of liquid air energy storage and data centers under off‐design thermodynamic operation

AIChE Journal, EarlyView.
Abstract The rapid growth of AI data centers (AIDCs) is intensifying stress on power systems and exposing operators to volatile electricity markets. This work develops a process‐informed co‐optimization framework that integrates liquid air energy storage (LAES) with AIDC operation. Unlike black‐box storage models, the proposed formulation captures LAES

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.

Gas‐Phase Residence Time Distribution Characteristics in a Gas–Liquid Stirred Tank With Multiple Impellers

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Residence time distribution (RTD) is a standard tool for characterizing the hydrodynamic performance of stirred tanks. In this work, gas‐phase RTD was experimentally investigated in a gas–liquid stirred tank equipped with six multiple‐impeller configurations using four impeller types (WH, HEDT, CBY, and PDT). The effects of impeller speed, gas

A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Spatial oxygen limitation is a major source of physiological stress and metabolic, scale‐dependent heterogeneity in aerobic bioprocesses. In gas‐liquid stirred tank reactors, oxygen availability is governed by hydrodynamics and mass transfer and is therefore inherently non‐uniform.

Thermal, environmental, and economic analysis of the gas turbine fogging system

Results in Engineering
Ambient temperature can be considered a critical indicator of the efficiency and power production of gas turbines, especially in hot areas, so compressor air inlet cooling systems have been widely used to mitigate this problem.

Measuring Corporate Alignment With the Circular Economy: a Text‐Based Circularity Index From Mandatory Non‐Financial Disclosures

Business Strategy and the Environment, EarlyView.
ABSTRACT The transition to a circular economy (CE) has become a strategic priority for firms, yet empirical assessments of corporate circularity remain fragmented and heavily dependent on structured indicators or self‐reported metrics. This paper proposes a novel, text‐based circularity index derived from mandatory non‐financial statements of large ...

An Indicator‐Based Decision Framework for Circular Bioeconomy Transition in the Steel Industry: Integrating Multiphase Learning and Cooperative Game Modelling

Business Strategy and the Environment, EarlyView.
ABSTRACT Despite growing attention to the circular bioeconomy (CBE), the steel industry currently lacks a standardised, sectoral measurement framework to facilitate a low‐carbon transition. In this study, a decision‐support framework for evaluating CBE performance in the steel industry is proposed.

Artificial Intelligence–Driven and Digital Practices for Circular Business and Finance: Insights for Advancing Hubs for Circularity

Business Strategy and the Environment, EarlyView.
ABSTRACT The emerging concept of Hubs for Circularity (H4Cs) presents an opportunity to create collaborative, self‐sustaining regional industrial ecosystems that drive circular economy transitions at scale. However, the operationalisation of H4Cs faces financial, organisational and data‐driven challenges.

Investor Perceptions of Climate Policy: Insights From the US Inflation Reduction Act

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper provides the first event study evidence on how the Inflation Reduction Act's (IRA) dedicated climate provisions reshaped equity valuations in the US carbon‐intensive sectors. Focusing on environmentally sensitive industries (ESI), we analyze cumulative abnormal returns around the four key IRA milestones in 2022–2023.
