A Numerical Investigation of the Effects of Piston Bowl Geometry and Spray Angle on Combustion, Performance and Emission of a Diesel Engine

open access: yesEnergy Science &Engineering, EarlyView.
A piston bowl's design and spray angle improve air‐fuel mixing, resulting in more complete combustion and higher efficiency. Ansys Forte 2023 R1 a CFD software was used to analyze the effects of five combustion chamber geometries of cylinder, modified re‐entrant, re‐entrant, double‐stepped, and stepped on engine performance, combustion, and emission ...

Deterministic Cost Estimation Approaches for Carbon Capture, Utilization, and Storage: A Review

open access: yesGreenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Carbon capture, utilization, and storage (CCUS) is regarded as a connection between traditional, high‐emission sectors and future green energy. This study encompasses literature from 2003 to early 2026 to review methodologies and formulae used for cost estimating in the various segments of carbon capture, transport, utilization, and storage ...

Revisiting the Nexus Between Trade Liberalisation and Income Inequality: The Case of Sub‐Saharan African Countries

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This paper examines the impact of trade liberalisation on income inequality across 24 Sub‐Saharan African (SSA) countries from 2000 to 2020. Using IV‐Tobit and 2SLS models, we consistently find that greater trade openness significantly exacerbates inequality in the region. Critically, we document an inverted U‐shaped relationship between trade

Elevator dynamic monitoring and early warning system based on machine learning algorithm

open access: yesIET Networks, EarlyView., 2022
In order to monitor and warn the elevator dynamics, in this work, the machine learning algorithm is introduced, and the particle swarm algorithm is used to perfect the model. The model is optimised, and the experimental comparison shows that the optimisation of the model parameters can further improve the accuracy of the elevator load prediction. Then,
