Evaluation of the approximated diffusion flamelet concept using fuels with different chemical complexity

Payri, F.; Novella Rosa, Ricardo; Pastor Enguídanos, José Manuel; Pérez-Sánchez, Eduardo Javier (Elsevier, 2017)

[EN] The ability of flamelet models to reproduce turbulent combustion in devices such as diesel engines or gas turbines has enhanced the usage of these approaches in Computational Fluid Dynamics (CFD) simulations. The ...
Fundamental insights on ignition and combustion of natural gas in an active fueled pre-chamber spark-ignition system

Rajasegar, Rajavasanth; Niki, Yoichi; García-Oliver, José M; Li, Zheming; Musculus, Mark P.B. (Elsevier, 2021-10)

[EN] Pre-chamber spark-ignition (PCSI), either fueled or non-fueled, is a leading concept with the potential to enable diesel-like efficiency in medium-duty (MD) and heavy-duty (HD) natural gas (NG) engines. However, the ...
Modeling of the nitrogen oxides formation process applicable to several diesel combustion modes

Redón Lurbe, Pau (Universitat Politècnica de València, 2013-11-04)

Como consecuencia de las exigentes legislaciones medioambientales actualmente en vigor, como las Euro Emission Standards en Europa, los investigadores e ingenieros se ven forzados a "re-desarrollar" el proceso de combustión ...
New 0-D methodology for predicting NO formation under continuously varying temperature and mixture composition conditions

Benajes Calvo, Jesus Vicente; López Sánchez, José Javier; Molina Alcaide, Santiago Alberto; Redón Lurbe, Pau (Elsevier, 2015-02)

The development of new diesel combustion modes characterized by low combustion temperatures, to minimize the NOx emissions, has caused a noticeable change in the diesel spray s structure and in the NOx chemistry, gaining ...
Thermal runaway evaluation and thermal performance enhancement of a lithium-ion battery coupling cooling system and battery sub-models
