A numerical study of the effect of nozzle diameter on diesel combustion ignition and flame stabilization

Desantes Fernández, José Mª; García-Oliver, José M; Novella Rosa, Ricardo; Pachano-Prieto, Leonardo Manuel (SAGE Publications, 2020-01)

[EN] The role of nozzle diameter on diesel combustion is studied by performing computational fluid dynamics calculations of Spray A and Spray D from the Engine Combustion Network. These are well-characterized single-hole ...
A two-equation soot-in-flamelet modeling approach applied under Spray A conditions

Pachano, Leonardo; Xu, Chao; García-Oliver, José M; Pastor Enguídanos, José Manuel; Novella Rosa, Ricardo; Kundu, Prithwish (Elsevier, 2021-09)

[EN] Soot production (including formation and oxidation) is studied in the transient, high-pressure and turbulent n -dodecane Spray A flames from the Engine Combustion Network (ECN) using computational fluid dynamics (CFD) ...
Analysis of the approximated diffusion flamelet approach using fuels with different chemical complexity

Pérez Sánchez, Eduardo Javier (Universitat Politècnica de València, 2015-07-17)

[EN[ This study is focused on a non-premixed combustion model based on the laminar flames, called flamelets, concept. Solving these flamelets can be very expensive in terms of computational cost so new assumptions must be ...
CFD modeling of combustion and soot production in Diesel sprays

Pachano Prieto, Leonardo Manuel (Universitat Politècnica de València, 2020-05-04)

[ES] En los últimos años, las emisiones de hollín provenientes de los motores de combustión interna han recibido más atención debido al impacto negativo que éstas tienen no solo en el ambiente, sino también en la salud del ...
Influence of the chemical mechanism in the frame of diesel-like CFD reacting spray simulations using a presumed PDF flamelet-based combustion model

Payri González, Francisco; García Oliver, José María; Novella Rosa, Ricardo; Pérez Sánchez, Eduardo Javier (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] The ability of a computational fluid dynamics (CFD) simulation to reproduce the diesel-like reacting spray ignition process and its corresponding flame structure strongly depends on both the fidelity of the chemical ...
LES study on spray combustion with renewable fuels under ECN Spray-A conditions

Mira Martínez, Daniel; Pérez-Sánchez, Eduardo J.; Surapaneni, Anurag; Benajes, Jesús; García-Oliver, José M; Pastor Enguídanos, José Manuel; De Leon-Ceriani, Daiana (American Society of Mechanical Engineers (ASME), 2021-10-15)

[EN] Poly-Oxymethylene Dimethyl Ethers (OMEx) are being intensively investigated because of their potentially renewable synthesis path, which make them suitable as liquid fuels for low-carbon transport applications. In the ...
Unsteady Flamelet modeling study on OMEx-type fuels under Engine Combustion Network Spray A conditions

Benajes, Jesús; García-Oliver, José M; Pastor Enguídanos, José Manuel; De Leon-Ceriani, Daiana (Elsevier, 2023-01-01)

[EN] Poly-Oxymethylene Dimethyl Ethers OMEx are synthetic and potentially-renewable fuels that lead to a notable reduction of the lifecycle CO2 emissions while promoting lower soot emissions than conventional Diesel fuel. ...
