Análisis termo-fluido-dinámico del flujo en una turbina radial de sobrealimentación mediante simulaciones CFD

Fajardo Peña, Pablo (Universitat Politècnica de València, 2011-09-06)

En este trabajo se ha realizado un estudio termo-fluido-dinámico de una turbina radial mediante el uso de mecánica de fluidos computacional. Ha sido necesario desarrollar nuevas condiciones de contorno para el código ...
Characterization of a radial turbocharger turbine in pulsating flow by means of CFD and its application to engine modeling

Galindo, José; Fajardo, Pablo; Navarro García, Roberto; García-Cuevas González, Luis Miguel (Elsevier, 2013-03)

This paper presents a numerical study analyzing the effect of pulsating flow in a variable geometry radial inflow turbine. The turbine behavior is analyzed under isentropic pulses, which are similar to those created by a ...
Diseño a escala de una turbina centrípeta para estudios aerodinámicos (modelado y experimental)

Santos Meléndez, Luis Fernando (Universitat Politècnica de València, 2017-07-27)

This work is part of a plan for a project whose objective is to determine the flow behavior in the volute channel and in the stator channels formed by the blades with which a centripetal turbine is composed. This study is ...
Diseño de volutas de compresores y turbinas radiales y cálculo del flujo en CFD

Korb, Alexey (Universitat Politècnica de València, 2019-10-11)

[ES] Los objetivos del proyecto son, en primer lugar desarrollar una herramienta de generación de geometrías de volutas de compresores y de turbinas radiales. Esta herramienta se realizará de manera analítica con el ...
Experimental approach for the analysis of the flow behaviour in the stator of a real centripetal turbine

Galindo, José; Tiseira, Andrés-Omar; García-Cuevas González, Luis Miguel; Hervás-Gómez, Natalia (SAGE Publications, 2021-06)

[EN] During normal operation, radial turbines may work in off-design conditions. Off-design conditions may be characterised by very low expansion ratios, very high expansion ratios, very low rotational speeds or very high ...
Methodology for the Numerical Characterization of a Radial Turbine under Steady and Pulsating Flow

Fajardo Peña, Pablo (Universitat Politècnica de València, 2012-07-26)

The increasing use of turbochargers is leading to an outstanding research to understand the internal flow in turbomachines. In this frame, computational fluid dynamics (CFD) is one of the tools that can be applied to ...
Radial turbine sound and noise characterisation with acoustic transfer matrices by means of fast one-dimensional models

Torregrosa, A. J.; García-Cuevas González, Luis Miguel; Inhestern, Lukas Benjamin; Soler-Blanco, Pablo (SAGE Publications, 2021-04-01)

[EN] Estimating correctly the turbine acoustics can be valuable during the engine design stage; in fact, it can lead to a more optimised design of the silencer and aftertreatment, as well as to better prediction of the ...
Set-up analysis and Optimization of CFD Simulations for Radial Turbines

Galindo, José; Hoyas, S; Fajardo, Pablo; Navarro, R. (2013-12)

[EN] This paper proposes a CFD method for simulating radial turbocharger turbine flows. A review is presented of the computational model in terms of meshing, mesh movement strategy, and computational algorithm in turbomachinery ...
Testing and modeling a reverse Brayton cryocooler using air as working fluid designed with automotive-related devices.

López Carrillo, Juan Antonio (Universitat Politècnica de València, 2022-10-27)

[ES] Se desarrollan en este trabajo el proceso de testeo y modelado de un turbogrupo de automoción para su uso en un ciclo Brayton inverso de refrigeración, su implementación en el ciclo junto a una campaña experimental ...
