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 ...
A numerical study of the complex flow structure in a compound meandering channel

Moncho Esteve, Ignacio José; García-Villalba, Manuel; MUTO Y.; SHIONO K.; Palau-Salvador, Guillermo (Elsevier, 2018)

[EN] In this study, we report large eddy simulations of turbulent flow in a periodic compound meandering channel for three different depth conditions: one in-bank and two overbank conditions. The flow configuration corresponds ...
Acoustic characteristics of a ported shroud turbocompressor operating at design conditions

Sharma, Sidharath; Broatch, A.; GARCIA TISCAR, JORGE; Allport, John M.; Nickson, Ambrose K. (SAGE Publications, 2020-10)

[EN] In this article, the acoustic characterisation of a turbocharger compressor with ported shroud design is carried out through the numerical simulation of the system operating under design conditions of maximum isentropic ...
Analysis of local extinction of a n-heptane spray flame using large-eddy simulation with tabulated chemistry

Benajes, Jesús; García-Oliver, José M; Pastor Enguídanos, José Manuel; Olmeda-Ramiro, Iván; Both, A.; Mira, D. (Elsevier, 2022-01)

[EN] This work is focused on the study of flame stabilization and local extinction of a spray flame in an atmospheric non-swirled test rig referred to as the CORIA Rouen Spray Burner. This burner shows a double reaction ...
Breakup dynamics in a pressure-swirl injector for urea-water solution applications: A computational study

Marco-Gimeno, Javier; Asztalos, Katherine J.; Moon, Chi Young; Powell, Christopher F.; Marti-Aldaravi, Pedro; Nocivelli, Lorenzo (SAGE Publications, 2024-10)

[ES] La cooptimización de la combustión dentro del cilindro y la tecnología de postratamiento se ha convertido en un aspecto clave en el diseño y desarrollo de motores, con el objetivo de cumplir con las normativas de ...
Large eddy simulation based on stabilized finite element method for the analysis of wind field around spatial structure

ZHOU, Dai; HUANG, Cheng (Editorial Universitat Politècnica de València, 2009-12-11)

This paper presents a stabilized finite element formulation for large eddy simulation to predict the turbulent flow with high Reynolds number, which can be applied for the simulation of wind field and wind pressure ...
LES Eulerian diffuse-interface modeling of fuel dense sprays near- and far-field

Desantes Fernández, José Mª; García-Oliver, José M; Pastor Enguídanos, José Manuel; Olmeda-Ramiro, Iván; Pandal, A.; Naud, B. (Elsevier, 2020-06)

[EN] Engine fuel spray modeling still remains a challenge, especially in the dense near-nozzle region. This region is difficult to experimentally access and also to model due to the complex and rapid liquid and gas ...
Modeling gaseous non-reactive flow in a lean direct injection gas turbine combustor through an advanced mesh control strategy

Payri, Raul; Novella Rosa, Ricardo; Carreres, Marcos; Belmar-Gil, Mario (SAGE Publications, 2020-09)

[EN] Fuel efficiency improvement and harmful emissions reduction are the main motivations for the development of gas turbine combustors. Numerical computational fluid dynamics (CFD) simulations of these devices are usually ...
Modeling internal flow and primary atomization in a simplex pressure-swirl atomizer

Ferrando, D.; Carreres, Marcos; Belmar-Gil, Mario; Cervelló-Sanz, D.; Duret, B.; Reveillon, J.; Salvador, Francisco Javier; Demoulin, F.X. (Begell House Inc., 2023-01-27)
