A new method to predict high and low-temperature ignition delays under transient thermodynamic conditions and its experimental validation using a Rapid Compression-Expansion Machine

Desantes Fernández, José Mª; Bermúdez, Vicente; López, J. Javier; López Pintor, Darío (Elsevier, 2016-09-01)

A new procedure to predict both high-temperature stage and cool flames ignition delays under transient thermodynamic conditions has been developed in this paper. The results obtained have been compared with those obtained ...
A phenomenological explanation of the autoignition propagation under HCCI conditions

Desantes, J.M.; López, J. Javier; García-Oliver, José M; López-Pintor, Darío (Elsevier, 2017)

[EN] A phenomenological explanation about the autoignition propagation under HCCI conditions is developed in this paper. To do so, diffusive effects from the burned zones to the fresh mixture, pressure waves based effects ...

Pans Alcaina, Daniel (Universitat Politècnica de València, 2022-07-28)

[ES] Este trabajo consiste en el estudio del proceso de combustión en una cámara de una máquina de compresión rápida o ¿RCEM¿ (Rapid Compression-Expansion Machine) utilizando como método de ignición diferentes geometrías ...
Experimental validation and analysis of seven different chemical kinetic mechanisms for n-dodecane using a Rapid Compression-Expansion Machine

Desantes, J.M.; López, J. Javier; García-Oliver, José M; López-Pintor, Darío (Elsevier, 2017-08)

[EN] Seven different chemical kinetic mechanisms for n-dodecane, two detailed and five reduced, have been evaluated under Engine Combustion Network (ECN) thermodynamic conditions by comparison to experimental measurements ...
Experimental validation of an alternative method to predict high and low-temperature ignition delays under transient thermodynamic conditions for PRF mixtures using a Rapid Compression-Expansion Machine

Desantes Fernández, José Mª; Bermúdez, Vicente; López, J. Javier; López Pintor, Darío (Elsevier, 2016-12-01)

An alternative procedure to predict both high-temperature stage and cool flames ignition delays under transient thermodynamic conditions is intended to be validated in this paper. An experimental study has been carried ...
Sensitivity analysis and validation of a predictive procedure for high and low-temperature ignition delays under engine conditions for n-dodecane using a Rapid Compression-Expansion Machine

Desantes, J.M.; Bermúdez, Vicente; López, J. Javier; López-Pintor, Darío (Elsevier, 2017-08-01)

[EN] A predictive procedure for cool flames and high-temperature ignition delays based on the accumulation and consumption of chain carriers has been validated for n-dodecane under engine conditions. To do so, an experimental ...
Study of the auto-ignition phenomenon of PRFs under HCCI conditions in a RCEM by means of spectroscopy

Desantes Fernández, José Mª; García Oliver, José María; Vera-Tudela-Fajardo, Walter Martin; López Pintor, Darío; Schneider, B.; Boulouchos, K. (Elsevier, 2016-10-01)

An investigation of the effects of contour conditions and fuel properties on the auto-ignition and combustion process under HCCI conditions is presented in this study. A parametric variation of initial temperature, intake ...
Theoretical and experimental study on the autoignition phenomena of homogeneous reactive mixtures

López Pintor, Darío (Universitat Politècnica de València, 2017-11-07)

The main objective of this Thesis is the study of the autoignition phenomenon of reactive mixtures from a theoretical and experimental point of view. A wide parametric study has been carried out in a Rapid Compression-Expansion ...
Theoretical development of a new procedure to predict ignition delays under transient thermodynamic conditions and validation using a Rapid Compression-Expansion Machine

Desantes Fernández, José Mª; López, J. Javier; Molina, Santiago; López Pintor, Darío (Elsevier, 2016-01-15)

An experimental and theoretical study about the autoignition phenomenon has been performed in this article. A new procedure to predict ignition delays under transient (i.e. variable) thermodynamic conditions has been ...
