Development of a test rig for the study of the atomization and combustion of a spray flame in an atmospheric annular spray burner at lean conditions

Cardona Vargas, Santiago (Universitat Politècnica de València, 2022-01-20)

[ES] El proceso de combustión en llamas de difusión de combustible atomizado es un fenómeno multifásico altamente complejo que a día de hoy no se comprende en su totalidad, ya que involucra varios eventos simultáneos, como ...
Experimental investigation of the lift-offheight and soot formation of a spray flame for different co-flow conditions and fuels

Gimeno, Jaime; Marti-Aldaravi, Pedro; Carreres, Marcos; Cardona-Vargas, Santiago (Elsevier, 2021-11)

[EN] Since the combustion process in spray flames is a highly complex multi-phase phenomenon, which involves several simultaneous processes such as atomization, vaporization, and chemical kinetics, it is still not fully ...
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 ...
Mixture formation and combustion process analysis of an innovative diesel piston bowl design through the synergetic application of numerical and optical techniques

Millo, F.; Piano, A.; Roggio, S.; Pastor, José V.; Micó, Carlos; De Vargas Lewiski, Felipe; Pesce, F.C.; Vassallo, A.; Bianco, A. (Elsevier, 2022-02-01)

[EN] The optimization of diesel engine piston bowl geometries has a crucial role in improving the near-wall flame evolution for better air/fuel mixing and soot reduction. With these aims, an innovative piston bowl for a ...
Study of ignition delay time and generalization of auto-ignition for PRFs in a RCEM by means of natural chemiluminescence

Desantes Fernández, José Mª; García Oliver, José María; Vera-Tudela-Fajardo, Walter Martin; López Pintor, Darío; Schneider, B.; Boulouchos, K. (Elsevier, 2016-03-01)

An investigation of the effects of contour conditions and fuel properties on ignition delay time under Homogeneous Charge Compression Ignition (HCCI) conditions is presented in this study. A parametric variation of initial ...
Verification of diesel spray ignition phenomenon in dual-fuel diesel-piloted premixed natural gas engine

Niki, Yoichi; Rajasegar, Rajavasanth; Li, Zheming; Musculus, Mark P.B.; García-Oliver, José M; Takasaki, Koji (SAGE Publications, 2022-02)

[EN] Dual-fuel (DF) engines, in which premixed natural gas and air in an open-type combustion chamber is ignited by diesel-fuel pilot sprays, have been more popular for marine use than pre-chamber spark ignition (PCSI) ...
