[ES] El principal objetivo de este trabajo es diseñar un ala para una aeronave de la que se conocen las especificaciones iniciales y comprobar mediante un análisis CFD que produce las prestaciones necesarias para mantener ...
Estudio computacional del flujo no reactivo en cámaras de combustión

Belmar Gil, Mario (Universitat Politècnica de València, 2018-10-17)

El presente Trabajo Fin de Master trata la resolución numérica mediante códigos CFD de una novedosa estrategia de inyección/combustión, conocida como Lean Direct Injection, aplicada a los motores de flujo continuo. Este ...
Influence of key geometrical features on the non-reacting flow of a Lean Direct Injection (LDI) combustor through Large-Eddy Simulation and a Design of Experiments

Carreres, Marcos; GARCIA TISCAR, JORGE; Belmar-Gil, Mario; Cervelló-Sanz, David (Elsevier, 2022-07)

[EN] Lean Direct Injection (LDI) emerged as an interesting concept to limit NOx emissions in aero engines at the cost of operating close to the flame lean blow-off limit. In this technology, fuel is injected into a swirled ...
Modal decomposition of the unsteady non-reactive flow field in a swirl-stabilized combustor operated by a Lean Premixed injection system

Salvador, Francisco Javier; Carreres, Marcos; GARCIA TISCAR, JORGE; Belmar-Gil, M. (Elsevier, 2021-05)

[EN] This work is focused on the numerical study of low-order coherent structures of a high-swirled laboratory-scaled combustor operated by a Lean Premixed (LP) injection system in non-reacting conditions through different ...
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)
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 ...
Thermal effects on the diesel injector performance through adiabatic 1D modelling. Part II: Model validation, results of the simulations and discussion

Payri, Raul; Salvador, Francisco Javier; Carreres, Marcos; Belmar-Gil, Mario (Elsevier, 2020-01-15)

[EN] In this paper, a one-dimensional computational model of the flow in a common-rail injector is used to compute local variations of fuel temperature (including the temperature change produced upon expansion across the ...
