Dynamic mode decomposition of the acoustic field in radial compressors

Broatch, A.; GARCIA TISCAR, JORGE; Roig-Villanueva, Ferran; Sharma, Sidharath (Elsevier, 2019-07)

[EN] Widely recognized since the beginning of air travel as a major issue, noise reduction remains nowadays a pressing concern for all stakeholders in the aviation industry. While aeroengine compressors, specially at the ...
Estudio CFD del impacto de la relación carrera/diámetro sobre el consumo y emisiones de un motor de automoción

Roig Villanueva, Ferran (Universitat Politècnica de València, 2016-09-19)

Proyecto confidencial (Riunet)
Experimental verification of hydrodynamic similarity in hot flows

Torregrosa, A. J.; Broatch, A.; GARCIA TISCAR, JORGE; Roig-Villanueva, Ferran (Elsevier, 2020-11-01)

[EN] This paper examines a common hypothesis in the design of internal combustion engine exhaust lines, namely that the ratio of the total pressure drop across the line to the inlet dynamic head should be a function only ...
Impact of simple surge-enhancing inlet geometries on the acoustic behaviour of a turbocompressor

Broatch, A.; Margot, Xandra; Garcia Tiscar, Jorge; Roig-Villanueva, Ferran (SAGE Publications, 2018)

[EN] This paper reports the results of an experimental campaign where four different inlet geometries for the compressor of an automotive turbocharger were acoustically characterized. These four geometries (a straight pipe ...
Impacto de la geometría de entrada sobre la acústica de turbocompesores de sobrealimentación

Roig Villanueva, Ferran (Universitat Politècnica de València, 2018-10-17)

Estudio experimental para la caracterización del campo fluido de entrada al turbocompresor con distintas geometrías simples de entrada y su correlación con el impacto sobre el ruido, márgen de bombeo y rendimiento. Se ...
On the Design of Heat Exchangers for Altitude Simulators

Broatch, A.; Olmeda, P.; GARCIA TISCAR, JORGE; Roig-Villanueva, Ferran (SAE International, 2021-04-15)

[EN] Altitude simulators for internal combustion engines are broadly used in order to simulate different atmospheric pressure and temperatures on a test bench. One of the main problems of these devices is their outlet ...
On the influence of inlet elbow radius on recirculating backflow, whoosh noise and efficiency in turbocharger compressors

Broatch, A.; Ruiz, S.; Garcia Tiscar, Jorge; Roig-Villanueva, Ferran (Elsevier, 2018)

[EN] While the influence of inlet geometry on turbocharger compressor behaviour has usually been investigated in terms of performance, surge margin and efficiency, data is scarce regarding the impact of the inlet flow field ...
On the Influence of Inlet Geometry on Turbocharger Compressor Noise

Roig Villanueva, Ferran (Universitat Politècnica de València, 2023-03-03)

[ES] En la sociedad actual hay cada vez una mayor conciencia de la importancia del calentamiento global. Esta preocupación se ve reflejada por los poderes legislativos de las naciones occidentales en normativas de emisiones ...
