Despite efforts to use ammonia as a fuel, there remain problems with low combustion speeds and high unburned (NH3) emissions. Therefore, methods compensate for slow stabilize have been studied. This study aims analyze how increasing the compression ratio affects engine performance enhance thermal efficiency reduce emissions in high-pressure direct injection spark-ignited engine. In addition, by applying high-flow-rate (HFR) injector, an improvement of fuel exhaust gas is observed through changes air–fuel mixture formation directly injected fuel. Compared existing ratio, incomplete loss due NH3 increases significantly, does not increase under increased ratio. When HFR injectors are applied net work 4.7%, energy losses reduced reducing amount NH3.

Comprehensive Overview of the Effective Thermal Conductivity for Hydride Materials: Experimental and Modeling Approaches

Energies, Год журнала: 2025, Номер 18(1), С. 194 - 194

Опубликована: Янв. 5, 2025

In metal hydride beds (MHBs), reaction heat transfer often limits the dynamic performance. Heat within MHB usually involves solid and gas phases. To account for both, an effective thermal conductivity (ETC) is defined. Measuring predicting ETC of primary importance when designing hydride-based systems high dynamics. This review paper presents integral overview experimental modeling approaches to characterize in MHBs. The most relevant methods measuring are described, results scopes shown. A comprehensive description models applied calculate MHBs under different conditions developed. Moreover, effects operation parameters such as P, T, composition on presented analyzed. Finally, a summary conclusions about techniques, historical with classification models, discussion needed parameters, comparison between calculated provided.
