Recent Advances in Machine Learning Research for Nanofluid-Based Heat Transfer in Renewable Energy System

Energy & Fuels, Journal Year: 2022, Volume and Issue: 36(13), P. 6626 - 6658

Published: June 13, 2022

Nanofluids have gained significant popularity in the field of sustainable and renewable energy systems. The heat transfer capacity working fluid has a huge impact on efficiency system. addition small amount high thermal conductivity solid nanoparticles to base improves transfer. Even though large research data is available literature, some results are contradictory. Many influencing factors, as well nonlinearity refutations, make nanofluid highly challenging obstruct its potentially valuable uses. On other hand, data-driven machine learning techniques would be very useful for forecasting thermophysical features rate, identifying most influential assessing efficiencies different primary aim this review study look at applications employed nanofluid-based system, reveal new developments research. A variety modern algorithms studies systems examined, along with their advantages disadvantages. Artificial neural networks-based model prediction using contemporary commercial software simple develop popular. prognostic may further improved by combining marine predator algorithm, genetic swarm intelligence optimization, intelligent optimization approaches. In well-known networks fuzzy- gene-based techniques, newer ensemble such Boosted regression K-means, K-nearest neighbor (KNN), CatBoost, XGBoost gaining due architectures adaptabilities diverse types. regularly used fuzzy-based mostly black-box methods, user having little or no understanding how they function. This reason concern, ethical artificial required.

A Prompt Decarbonization Pathway for Shipping: Green Hydrogen, Ammonia, and Methanol Production and Utilization in Marine Engines

Atmosphere, Journal Year: 2023, Volume and Issue: 14(3), P. 584 - 584

Published: March 17, 2023

The shipping industry has reached a higher level of maturity in terms its knowledge and awareness decarbonization challenges. Carbon-free or carbon-neutralized green fuel, such as hydrogen, ammonia, methanol, are being widely discussed. However, little attention paid to the fuel pathway from renewable energy shipping. This paper, therefore, provides review production methods for power (green methanol) analyzes potential application shows that methanol (1) hydrogen seawater electrolysis using power; (2) ammonia + Haber–Bosch process; (3) CO2 power. While future is bright, short term, costs expected be than conventional fuel. Our recommendations therefore follows: improve technology reduce cost; develop electrochemical increase efficiency production; explore new technology. Strengthening research development expanding capacity ensure an adequate supply low- zero-emission marine important factors achieve carbon reduction

Improving the combustion and emission performance of a diesel engine powered with mahua biodiesel and TiO2 nanoparticles additive

Alexandria Engineering Journal, Journal Year: 2023, Volume and Issue: 72, P. 387 - 398

Published: April 17, 2023

The dwindling air quality and diminishing fossil fuel reserves have led to an increase in the need for alternative sources of fuel. Biodiesel derived from animal/plant seems be attractive substitution. However, there are some shortcomings biodiesel like lower thermal efficiency, poor atomization, inferior heating value, higher molecular mass. One probable novel ways address this lacuna is by use nano based IC engine. present study performs endeavor improve performance emulsion qualities generated mahua oil employing Titanium oxide (TiO2) nanoparticles as additive. All trials were conducted a diesel-powered engine at varying load levels with different test such diesel fuel, blended (80 % + 20 biodiesel), nanoparticle-based – 200 mg/L TiO2). When compared mode, average CO emission reduction 37.42 46.54 %, respectively. In comparison HC 22.54 28.4 biodiesel, NOx 4 2.3
