Decoding the Circular Economy Job Market in the EU: A Quantitative and Comparative Analysis

Business Strategy and the Environment, EarlyView.
ABSTRACT The circular economy (CE) is increasingly promoted as a pathway to sustainable development, yet systematic evidence on the structure of the CE labor market remains limited. Little is known about how CE‐related job opportunities are distributed across countries, which job characteristics dominate this market, and how such patterns compare with ...

Ignition characteristics of a high-energy jet plasma igniter in an aeroengine afterburner

Propulsion and Power Research
With the increasing thrust-to-weight ratio demands of modern aeroengines, afterburner ignition performance requirements have become more stringent. To broaden the ignition boundary and enhance ignition capability under extreme conditions, a high-energy ...

Influence of the thickness absorbing film on the PETN ignition threshold by a laser pulse

MATEC Web of Conferences, 2015
Numerical simulation of the PETN ignition by a film, which is heated by a laser pulse was conducted. There are shown that dependence of threshold energy of ignition of PETN by a laser pulse has a linear dependence from the thicknesses of the absorbing ...

Methanol With Increased Water Content in Internal Combustion Engines

Chemie Ingenieur Technik, EarlyView.
This study investigates the potential to improve overall Well‐to‐Wheel efficiency by using low‐purity methanol from synthesis of hydrogen and furnace gas as CO2‐source. Combustion efficiency is comparable to pure methanol, while distillation energy could be saved.

Laminar Burning Velocity of Ammonia‐Hydrogen Mixtures Predicted by Machine Learning

Chemie Ingenieur Technik, EarlyView.
Ammonia–hydrogen blends aid defossilization, but slow combustion kinetics require complex modeling. Although chemical kinetic modeling is computationally expensive, machine learning surrogates offer fast predictions. This study trained GPR, DT, and ANN models on 1445 experimental points.

Flame morphology and laminar flame assessments affected by flames interaction using multi-ignition sources of NH3/H2-air flames

Applications in Energy and Combustion Science
A detailed assessment of flame–flame interaction and laminar flame evolution using multi-ignition sources is experimentally studied. To understand the flame interaction, the centrally ignited flame is measured and calculated for comparison with multi ...

Design and implementation of a 3D‐printed modular distillation tower for experimental teaching in chemical engineering

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Several authors have reported the disconnection between the skills, abilities, and attitudes of graduates from STEM careers with the current needs of the labour market. In science and engineering fields, research has found the need for interdisciplinary approaches that encourage meaningful learning.
