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 soot formation in a lab-scale Rich-Quench-Lean combustor using LES with tabulated chemistry

Pachano-Prieto, Leonardo Manuel; Kalbhor, Abhijit; Mira, Daniel; Van-Oijen, Jeroen (Elsevier, 2024)

[EN] A numerical study of the effects of air dilution on soot formation and particle dynamics in a lab-scale rich-quench-lean (RQL) combustor is presented using large-eddy simulations (LES) with tabulated chemistry. The ...
Análisis de la interacción de los procesos de inyección y combustión con el campo de velocidad dentro del cilindro en motores de encendido por compresión

Pachano Prieto, Leonardo Manuel (Universitat Politècnica de València, 2017-07-27)

Emission legislation together with the need of more fuel-efficient engines have driven the development of promising combustion concepts in compression ignition (CI) engines. Most of them, lead toward a lean and low temperature ...
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 ...
Combined experimental and numerical studies on soot characteristics of diesel sprays with split injection strategies

Xuan, Tiemin; Maes, Noud; García-Oliver, José M; De Leon-Ceriani, Daiana; Pachano-Prieto, Leonardo Manuel; He, Zhixia (Elsevier, 2022-12)

[EN] Experimental and numerical studies on the soot characteristics of Spray A flames were conducted with a focus on the effects of different split injection strategies in high-pressure high-temperature vessels within the ...
Computational study of ECN Spray A and Spray D combustion at different ambient temperature conditions

García-Oliver, José M; Novella Rosa, Ricardo; Pastor Enguídanos, José Manuel; Pachano-Prieto, Leonardo Manuel (Elsevier, 2020-12)
