A critical analysis of the AHRI polynomials for scroll compressor characterization

Marchante-Avellaneda, Javier; Corberán, José M.; Navarro-Peris, Emilio; SHRESTHA (Elsevier, 2023-01-25)

[EN] This paper presents the analysis of the energy consumption and mass flow rate of scroll-type compressors. The study has included the data of several AHRI reports (especially AHRI 11 and AHRI 21) and data from other ...
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 ...
An experimental study of gasoline effects on injection rate, momentum flux and spray characteristics using a common rail diesel injection system

Payri, Raul; García Martínez, Antonio; Domenech Llopis, Vicente; Durrett, Russell; Plazas, Alejandro H. (Elsevier, 2012-07)

A comparative study using diesel fuel and gasoline has been conducted focusing on the injection process. In this paper an experimental study has been carried out comparing the effects of the different fuels on the mass ...
Analysis of alternatives in the high pressure turbine of the Kr ko nuclear power plant

Jorge López, Francisco Javier (Universitat Politècnica de València, 2022-11-02)

[ES] El trabajo consiste en la simulación termohidráulica del sistema secundario de la central nuclear de Eslovenia ya que se va a proceder al cambio de la turbina principal de alta presión por una más moderna. El objetivo ...
Design and implementation of the control system of an equipment aimed at reproducing variable environmental conditions on internal combustion engine tests

Blas Medina, Sergio (Universitat Politècnica de València, 2019-10-18)

[ES] Este proyecto presenta un equipo que permite reproducir las condiciones de presión, temperatura y humedad deseadas para emular condiciones de ensayo de motores de combustión. Durante el trabajo se detallan el principio ...
Development of compact empirical models for variable-speed compressors for the prediction of energy consumption, mass flow and discharge temperature

Ossorio-Santiago, Rubén Josep; Marchante-Avellaneda, Javier; Navarro-Peris, Emilio (Elsevier, 2024-05-01)

[EN] In the context of heat pumps, developing prediction models for compressor performance holds significant importance for design, selection, control, and fault detection. Nevertheless, there is not currently an established ...
Diseño y dimensionado de una batería de cuatro silos para cebada en Paterna (Valencia)

Sanz Pulido, Aída (Universitat Politècnica de València, 2019-07-30)

[ES] Siguiendo la Orden CIN/323/2009, de 9 de febrero, donde se establecen los requisitos para la verificación de los títulos universitarios, en cuanto al trabajo final de grado; se va a realizar el diseño de una batería ...
Influence of biofuels on the internal flow in diesel injector nozzles

Salvador, F.J.; Martínez López, Jorge; Romero Bauset, José Vicente; Roselló, M.D. (Elsevier, 2011)

[EN] In this paper, the behavior of the internal nozzle flow of a standard diesel fuel has been compared against a biodiesel fuel (soybean oil) at cavitating and non-cavitating conditions, using a homogeneous equilibrium ...
Numerical simulation and extended validation of two-phase compressible flow in diesel injector nozzles

Salvador Rubio, Francisco Javier; Hoyas, S; Novella Rosa, Ricardo; Martínez López, Jorge (Professional Engineering Publishing, 2011)

In this paper, the ability of a computational fluid dynamics code to reproduce cavitation phenomena accurately is checked by comparing data acquired by numerical simulations against those obtained from different experiments ...
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 ...
