Análisis del flujo no reactivo e inyección líquida de combustible en cámaras de combustión mediante Mecánica de Fluidos Computacional

Olmeda Ramiro, Iván (Universitat Politècnica de València, 2020-12-19)

[ES] El estudio sobre los sistemas de combustión y la inyección de combustibles líquidos es un tema fundamental para el diseño de novedosos sistemas de propulsión, entre los que se encuentra el concepto Lean Direct Injection ...
Computational study of the cavitation phenomenon and its interaction with the turbulence developed in diesel injector nozzles by Large Eddy Simulation (LES)

Salvador Rubio, Francisco Javier; Martínez López, Jorge; Romero Bauset, José Vicente; Roselló Ferragud, María Dolores (Elsevier, 2013-04)

Firstly, the code has been validated at real operating diesel engine conditions with experimental data in terms of mass flow, momentum flux and effective velocity, showing that the model is able to predict with a high level ...
Computational study of the Premixed Charge Compression Ignition combustion in a Rapid Compression Expansion Machine: Impact of multiple injection strategy on mixing, ignition and combustion processes

Martínez, María; Altantzis, Christos; Wright, Yuri M.; Marti-Aldaravi, Pedro; Boulouchos, Konstantinos (Elsevier, 2022-06-15)

[EN] Combustion processes operating under the low-temperature (LTC) are a promising alternative for internal combustion engines, achieving high efficiency and low emissions within the legislative framework. Under this field ...

Large Eddy Simulation for high pressure flows: Model extension for compressible liquids

Payri, Raul; Tormos, B.; Gimeno, Jaime; Bracho Leon, Gabriela (PERGAMON-ELSEVIER SCIENCE LTD, 2011)

[EN] The present study gives a general outline for the fluid-dynamical calculation of flows at high pressure conditions. The main idea is to present a mathematical description of high pressure processes in liquids at ...
Large eddy simulations of atomisation and sprays: application to a high pressure multihole injector

Chausserie-Laprée, Paul; Hélie, Jérome; Chesnel, Jeremy; Demoulin, François-Xavier (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] A weak coupling strategy is proposed to simulate the pressurised spray without any empirical readjustment. Volume Of Fluid is used to simulate the nozzle internal flow with cavitation and its primary atomization into ...
Spectral analysis and modelling of the spray liquid injection in a Lean Direct Injection (LDI) gas turbine combustor through Eulerian-Lagrangian Large Eddy Simulations

Broatch, A.; Carreres, Marcos; GARCIA TISCAR, JORGE; Belmar-Gil, M. (Elsevier, 2021-11)

[EN] The main challenge of next-generation aeronautical gas turbine engines lies in the increase of the efficiency of the cycle and the reduction of pollutant emissions below stringent restrictions. This has led to the ...
