A large-eddy simulation of diesel-like gas jets

Hoyas, S; Gil, A.; Mompó Laborda, Juan Manuel; Khuong ., Anh Dung (Inderscience, 2011)

[EN] Some aspects of the transient evolution of diesel-like gas jets by means of large-eddy simulation (LES) are discussed in this work. In order to understand the relationship between the inlet boundary condition and the ...
Analysis of transient liquid and vapor phase penetration for diesel sprays undervariable injection conditions

Pastor Soriano, José Vicente; Payri Marín, Raúl; García Oliver, José María; Briceño Sánchez, Francisco Javier (Begell House, 2011)

The objective of this study is to investigate liquid length and vapor penetration for diesel sprays under highly transient injection conditions. High-speed Mie-scattering and shadowgraphy imaging of the spray evolution ...
Aplicación de la visualización de la combustión con cámara rápida a la comparación de combustibles de origen renovables

Rubio Jiménez, Marcos (Universitat Politècnica de València, 2020-05-12)

[ES] Durante los últimos años las leyes sobre contaminación cada vez son más restrictivas y esto lleva a ingenieros e investigadores a buscar soluciones que cumplan con la normativa establecida. Una de las estrategias ...
Aplicación de un modelo 1D de chorros a la predicción del autoencendido en condiciones de motores Diesel

Mora Morató, Joaquín (Universitat Politècnica de València, 2019-09-17)

[ES] El modelado de chorros permite describir el comportamiento del combustible al ser inyectado en la cámara de combustión de los motores de encendido por compresión, con implicaciones importantes sobre las prestaciones ...
Engine combustion network (ECN): measurements of nozzle geometry and hydraulic behavior

Kastengren, Alan L; Tilocco, F. Zak; Powell, Christopher F.; Manin, Julien; Pickett, Lyle; Payri Marín, Raúl; Bazyn, Tim (Begell House, 2012)

[EN] Despite the importance of sprays to engine combustion, understanding has been hampered by the sensitivity of spray behavior to unknown nozzle geometry effects. The Engine Combustion Network (ECN) collaboration has ...
Estimation of a suitable Schmidt number range in diesel sprays at high injection pressure

Salvador Rubio, Francisco Javier; Ruiz Rosales, Santiago; Gimeno, Jaime; De La Morena Borja, Joaquín (Elsevier, 2011-09)

The aim of this paper is to estimate a suitable range for the Schmidt number value in non-evaporative diesel sprays. For this purpose, mass distribution data obtained from X-ray absorption experiments existing in literature ...
Fuel concentration in isothermal Diesel sprays through structured planar laser imaging measurements

Payri, Raul; Gimeno, Jaime; Marti-Aldaravi, Pedro; Manin, J. (ELSEVIER SCIENCE INC, 2012)

[EN] The mixing of isothermal liquid sprays in engine-like conditions has been investigated by applying the structured planar laser imaging technique to remove multiple light scattering. The intensity of the illumination ...
In-flame soot quantification of diesel sprays under sooting/non-sooting critical conditions in an optical engine

Xuan, Tiemin; Pastor, José V.; García-Oliver, José M; García Martínez, Antonio; He, Zhixia; Wang, Qian; Reyes, Miriam (Elsevier, 2019-02-25)

[EN] Because of the challenge of meeting stringent emissions regulations for internal combustion engines, some advanced low temperature combustion modes have been raised in recent decades to improve combustion efficiency ...
Methodology for Phase Doppler Anemometry Measurements on a Multi-Hole Diesel Injector

Payri, Raul; Gimeno, Jaime; Marti-Aldaravi, Pedro; GIRALDO-VALDERRAMA, JHOAN SEBASTIAN (Springer-Verlag, 2017)

[EN] In this paper, a methodology for Phase Doppler Anemometry (PDPA) measurements on a multi-hole diesel injector is developed. Several key considerations were taken into account in this methodology: The windows for PDPA ...
