A numerical approach for predicting flow-induced acoustics at near-stall conditions in an automotive turbocharger compressor

Navarro García, Roberto (Universitat Politècnica de València, 2014-11-13)

Se realiza un modelo CFD-3D de un compresor centrífugo. Se determina la configuración numérica adecuada para simular puntos de funcionamiento cercanos a bombeo. Se validan los resultados frente a ensayos experimentales ...
Análisis estático no lineal (pushover) de estructura aporticada de hormigón armado con diferentes grados de ductilidad. Aplicando la Norma Sismorresistente Colombiana 2010 (NSR-10)

González Torres, Camilo Andrés (Universitat Politècnica de València, 2018-04-12)

El presente trabajo final de máster consiste en el análisis de la importancia de la ductilidad en el diseño estructural sísmico de un proyecto típico de estructuras con un sistema de pórticos en hormigón armado, tomando ...
Computational Study of the Transonic Flow over a Swept Wing

Quintero Rodríguez, Fabián Alexis (Universitat Politècnica de València, 2020-03-31)

[ES] La interacción entre la onda de choque y la capa límite puede producir separación del flujo o fenómenos no estacionarios, reduciendo el rendimiento aerodinámico del ala o poniendo en riesgo su integridad estructural. ...
Discrete Event Simulation as tool for the decision-making process in an ETO company

Senén Cerdà, Víctor (Universitat Politècnica de València, 2023-07-04)

[ES] Esta tesis es el resultado de una experiencia realizada durante el Industrial Management Laboratory, realizado por el Politecnico di Milano en colaboración con la empresa ICI Caldaie Spa, una empresa de manufacturing ...
Evaluation of modelling parameters for computing flow-induced noise in a small high-speed centrifugal compressor

Sharma, Sidharath; GARCIA TISCAR, JORGE; Allport, John M.; Barrans, Simon; Nickson, Ambrose K. (Elsevier, 2020-03)

[EN] Developments in computing infrastructure and methods over the last decade have enhanced the potential of numerical methods to reasonably predict the aerodynamic noise. The generation and propagation of the flow induced ...
Influence of tip clearance on flow behavior and noise generation of centrifugal compressors in near-surge conditions

Galindo, José; Tiseira Izaguirre, Andrés Omar; Navarro García, Roberto; López Hidalgo, Miguel Andrés (Elsevier, 2015-04)

CFD has become an essential tool for researchers to analyze centrifugal compressors. Tip leakage flow is usually considered one of the main mechanisms that dictate compressor flow field and stability. However, it is a ...
Numerical and experimental analysis of automotive turbocharger compressor aeroacoustics at different operating conditions

Broatch Meza, Alberto; Galindo, José; Navarro García, Roberto; García Tíscar, Jorge (Elsevier, 2016-10)

Centrifugal compressor aeroacoustics are analyzed by means of a three-dimensional CFD model. Three operating points at nominal compressor speed are simulated ranging from best efficiency point to near-surge conditions. ...
Simulations and measurements of automotive turbocharger compressor whoosh noise

Broatch Jacobi, Jaime Alberto; Galindo, José; Navarro García, Roberto; García Tíscar, Jorge; Daglish, Andrew; Sharma, Raj K. (Taylor & Francis, 2015)

Turbocharger noise has become a major concern in downsized automotive engine development. In this paper, the analysis is focused on the whoosh noise produced by the compressor when it is working near surge. A centrifugal ...
