A Robust Adiabatic Model for a Quasi-Steady Prediction of Far-Off Non-Measured Performance in Vaneless Twin-Entry or Dual-Volute Radial Turbines

Serrano, J.R.; Arnau Martínez, Francisco José; García-Cuevas González, Luis Miguel; Samala, Vishnu (MDPI AG, 2020-03)

[EN] The current investigation describes in detail a mass flow oriented model for extrapolation of reduced mass flow and adiabatic efficiency of double entry radial inflow turbines under any unequal and partial flow admission ...
A zonal approach for estimating pressure ratio at compressor extreme off-design conditions

Galindo, José; Navarro, Roberto; García-Cuevas González, Luis Miguel; Tarí, Daniel; Tartoussi, H.; Guilain, S. (SAGE Publications, 2019-04)

[EN] Zero-dimensional/one-dimensional computational fluid dynamics codes are used to simulate the performance of complete internal combustion engines. In such codes, the operation of a turbocharger compressor is usually ...
Combustion noise analysis of partially premixed combustion concept using gasoline fuel in a 2-stroke engine

Broatch Jacobi, Jaime Alberto; Margot , Xandra; Novella Rosa, Ricardo; Gómez-Soriano, Josep (Elsevier, 2016-07-15)

In the last decade, different advanced combustion concepts based on generating totally or partially premixed conditions have been investigated in CI (compression ignition) engines with the aim of achieving lower NOx ...
Effects of multiple injection strategies on gaseous emissions and particle size distribution in a two-stroke compression-ignition engine operating with the gasoline partially premixed combustion concept

Bermúdez, Vicente; Ruiz-Rosales, Santiago; Novella Rosa, Ricardo; Soto-Izquierdo, Lian (SAGE Publications, 2018)

[EN] In order to improve performance of internal combustion engines and meet the requirements of the new pollutant emission regulations, advanced combustion strategies have been investigated. The newly designed partially ...
Evaluation of the Eulerian Lagrangian Spray Atomization (ELSA) model in spray simulations: 2D cases

Hoyas, S; Gil Megías, Antonio; Margot, Xandra Marcelle; Khuong-Anh, Dung; Ravet, Frederic (Elsevier, 2013-04)

[EN] The aim of this paper is the evaluation and validation of the Eulerian-Lagrangian Spray Atomization (ELSA) model implemented in a CFD code by Renault. ELSA is an integrated model for capturing the whole spray evolution, ...
Evaluation of the Eulerian-Lagrangian spray atomisation (ELSA) in spray simulations

Hoyas, S; Pastor Enguídanos, José Manuel; Khuong ., Anh Dung; Mompó Laborda, Juan Manuel; Ravet, Frederic (Inderscience, 2011)

[EN] Many approaches have been used to simulate the spray structure especially in modelling fuel sprays, i.e., Eulerian, Lagrangian, Lagrangian- Eulerian, Eulerian-Eulerian and Eulerian-Lagrangian approaches. The present ...
Impact of injection settings operating with the gasoline Partially Premixed Combustion concept in a 2-stroke HSDI compression ignition engine

Benajes, Jesús; Novella Rosa, Ricardo; De Lima, D.; Thein, Kévin Jean Lucien (Elsevier, 2017-05-01)

[EN] Partially Premixed Combustion (PPC) using gasoline-like fuels has proven its potential to control or even break the NOx and soot emissions trade-off, retaining the high efficiency levels characteristic of the conventional ...
Implementation of the Partially Premixed Combustion concept in a 2-stroke HSDI diesel engine fueled with gasoline

Benajes Calvo, Jesus Vicente; Molina Alcaide, Santiago Alberto; Novella Rosa, Ricardo; De Lima Moradell, Daniela Andreina (Elsevier, 2014-06-01)

Partially Premixed Combustion (PPC) of fuels in the gasoline octane range has proven to combine low NOX and soot emissions with high indicated efficiencies, while still retaining control over combustion phasing with the ...
Thermographic study of the preheating plugs in diesel engines

Royo Pastor, Rafael; Albertos Arranz, M.A.; Cárcel Cubas, Juan Antonio; Payá Herrero, Jorge (Elsevier, 2012)

The use of direct injection diesel engines has been widely applied during the past ten years. In such engines, the preheating plugs are a key element which has a significant contribution in the pollutant emissions. In ...
Understanding the performance of the multiple injection gasoline partially premixed combustion concept implemented in a 2-Stroke high speed direct injection compression ignition engine

Benajes Calvo, Jesus Vicente; Martín Díaz, Jaime; Novella Rosa, Ricardo; Thein, Kévin Jean Lucien (Elsevier, 2016-01-01)

The newly designed Partially Premixed Combustion (PPC) concept operating with high octane fuels like gasoline has confirmed the possibility to combine low NOx and soot emissions keeping high indicated efficiencies, while ...
