A physically based methodology to extrapolate performance maps of radial turbines

Payri González, Francisco; Serrano Cruz, José Ramón; Fajardo, Pablo; Reyes Belmonte, Miguel Ángel; Gozalbo Belles, Ricardo (Elsevier, 2012-03)

This paper details a physically based methodology to perform an extrapolation of the radial turbine performance maps, both mass flow characteristics and the efficiency curve. This method takes into account a narrow range ...
Contribution to the Modeling and Understanding of Cold Pulsating Flow Influence in the Efficiency of Small Radial Turbines for Turbochargers

Serrano Cruz, José Ramón; Arnau Martínez, Francisco José; Fajardo, Pablo; Reyes Belmonte, Miguel Ángel; Vidal, Fabrice (American Society of Mechanical Engineers (ASME), 2012-10)

In the present paper, an unsteady approach to determine the performance of a small radial inflow turbine working under cold pulsating flow is presented. It has been concluded that a reasonably good characterization of ...
HD Diesel engine equipped with a bottoming Rankine cycle as a waste heat recovery system. Part 2: Evaluation of alternative solutions

Serrano Cruz, José Ramón; Dolz Ruiz, Vicente; Novella Rosa, Ricardo; García Martínez, Antonio (Elsevier, 2012-04)

A theoretical investigation has been performed on the feasibility of introducing a waste heat recovery (WHR) system in a two-stage turbocharged HDD engine. The WHR is attained by introducing a Rankine cycle, which uses an ...
Potential of using a nozzle at the compressor inlet of a high-speed direct-injection diesel engine

Desantes, J.M.; Luján, José M.; Plá Moreno, Benjamín; Soler Muniesa, José Antonio (SAGE Publications, 2011)

[EN] The present work reports the effect of a nozzle placed upstream of the compressor of a high-speed direct-injection diesel engine. It has been observed that mounting a nozzle at the compressor inlet can lead to a shift ...
Study of turbocharger shaft motion by means of non-invasive optical techniques: Application to the behaviour analysis in turbocharger lubrication failures

Pastor, José V.; Serrano, J.R.; Dolz, Vicente; López Hidalgo, M.A.; BOUFFAUD, F. (ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2012)

[EN] This paper presents a novel non-invasive technique to estimate the turbocharger shaft whirl motion. The aim of this article is to present a system for monitoring the shaft motion of a turbocharger, which will be used ...
Turbine adapted maps for turbocharger engine matching

Tancrez, M; Galindo, José; Guardiola, Carlos; Fajardo, Pablo; VARNIER, OLIVIER (Elsevier, 2011-01)

This paper presents a new representation of the turbine performance maps oriented for turbocharger characterization. The aim of this plot is to provide a more compact and suited form to implement in engine simulation models ...
