Article
In this work cyclic variability is examined in a methane-fueled spark-ignition (SI) engine. A new numerical approach is developed and integrated into the ignition model of an in-house computational fluid dynamics (CFD) code, with the aim to estimate the effect of this highly-complex phenomenon in engines. This sub-model focuses on small-scale turbu...
Chapter
The motivation of the present work is first to conduct the validation of a Computational Fluid Dynamics (CFD) code, for different methane-hydrogen fuel blends in a spark-ignition (SI) engine, focusing on the newly developed combustion model. This validation is based on both performance and emissions comparison with experimental data, in order to ga...
Article
The main scope of the present work is to examine the combustion processes inside the cylinder of a spark-ignition (SI) engine fueled with a methane-hydrogen blend with variable equivalence ratio. This combustion analysis is conducted with a computational fluid dynamics code, which is an in-house code and has been initially developed for simulating...

Combustion results obtained from a spark ignition engine fueled with two synthetic gases obtained from catalytic decomposition of biogas are presented in this paper. These results are compared with those obtained when the engine was fueled with gasoline, methane and with the biogas from which synthetic gases are extracted. Experimental tests were p...
Article
Catalytic Decomposition of Biogas (CDB), producing simultaneously syngases (SG), with high hydrogen contents, for spark ignition (SI) engines and bio-carbon nanofibers (BCNFs) to be further used as precursor of synthetic graphite, is presented as an alternative to the usual direct combustion. Synthetic biogas mixtures were decomposed in the presenc...

Viriato fue uno de los supervivientes de la matanza del pretor de la Hispania Ulterior, S. Sulpicius Galba, pero se ignora la fecha y el lugar de su nacimiento. La tradici?n hist?rica lo ha convertido sistem?ticamente en un pastor de ganado, pero los trazos sobre su personalidad (sobriedad, energ?a, justicia, fidelidad) permiten considerarlo como u...
Article
In this work, the performance of carbon black catalysts in the catalytic decomposition of methane (CDM) was studied in a fluidized-bed reactor (FBR). Carbon black catalysts have recently gained attention for the CDM because of their relatively high stability and efficiency. The use of fluidized bed reactors may allow for the implementation of CDM o...

De acuerdo con su estructura y disposición morfológica, la mayoría de las regiones que podemos agrupar en la «Cuenca Alta del Guadalquivir», corresponden básicamente a las actuales provincias de Jaén, Granada y Córdoba, sobre todo las tierras situadas a ambas vertientes del río, junto a la falla de Sierra Morena al Norte y el Sistema Subbético al S...
Article
A model has been developed in order to analyse the influence of friction and heat transfer between the exhaust gases and the inside wall of the exhaust manifold on spark ignition engine performance. One-dimensional unsteady compressible flow equations are used to describe instantaneous evolution of the flow inside the manifolds. Special attention i...

Starting from the significant discovery of the most of the bronze from Osuna, studied by ManuelRodríguez de Berlanga in the first half of the Nineteenth Century, the authors develop an analysis about theimportance of those works for the knowledge of the Roman world History. It is not made from an unique pointof view; the approach is complemented with...
