[EN] There is a growing concern about the feasibility of a new generation of internal combustion engines in a low-temperature and efficient way that can meet the emission regulations while maintaining the desirable power ...

[ES] Este trabajo estará dedicado a la evaluación de dos estrategias novedosas en el sistema de turbosobrealimentación de un motor de combustión interna. En particular, se evaluarán dos motores diferentes: un motor diesel ...

Although high-pressure exhaust gas recirculation has been commonly used in turbocharged diesel engines for controlling the NOx formation, recent advances in after-treatment and material technology make possible using a ...

[EN] In commonly applied one-dimensional choking models for radial turbines, choked flow is assumed to appear in the geometrical throat of each stator and rotor. Coupled and complex three-dimensional effects are not ...

[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 ...

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 ...

[ES] Teniendo en cuenta la preocupación por la reducción de emisiones en el sector marítimo, el presente trabajo evalúa, mediante modelado y simulación, la oxicombustión en un motor de barco de dos tiempos (2SE) y la mejor ...

[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 ...
