A new approach to modelling the two way coupling for momentum transfer in a hollow-cone spray

Papoutsakis, Andreas; Sazhin, Sergei; Begg, Steven; Danaila, Ionut; Luddens, Francky (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] A new approach to modelling the interaction between droplets and the carrier phase is suggested. The new model is applied to the analysis of a spray injected into a chamber of quiescent air, using an Eulerian-Lagrangian ...
Aplicación y evaluación de un modelo eulerianolagrangiano de atomización de chorros en simulaciones CFD de chorros Diesel

Khuong ., Anh Dung (Universitat Politècnica de València, 2012-05-07)

En esta tesis se evalúa y valida el modelo de atomización ELSA en motores Diesel.
Boundary condition and fuel composition effects on injection processes of high-pressure sprays at the microscopic level

Manin, J.; Bardi, M.; Pickett, L. M.; Payri Marín, Raúl (Elsevier, 2016-07)

Detailed imaging of n-dodecane and ethanol sprays injected in a constant-flow, high-pressure, high-temperature optically accessible chamber was per-formed. High-speed, diffused back-illuminated long-distance microscopy was ...
Desarrollo y aplicación de un modelo CFD avanzado para chorros de combustible

Carrillo Cayuela, Jaime (Universitat Politècnica de València, 2018-11-20)

[ES] El alumno se encargará de optimizar un modelo de evaporación tipo LHF para sprays, tanto física como numéricamente, implementado en un código CFD. Posteriormente se aplicará para realizar simulaciones de mezcla ...
Determination of the optical depth of a DI diesel spray

Payri González, Francisco; Pastor, Jose V.; Payri, Raul; Manin, Julien Luc (Springer Verlag (Germany), 2011-06)

The optical depth is responsible of limiting the optical diagnostic using visible wavelength in the sprays. This paper proposes to measure the optical depth directly in a real Diesel spray through line-of-sight laser ...
Effect of the nozzle holder on injected fuel temperature for experimental test rigs and its influence on diesel sprays

Gimeno, Jaime; Marti-Aldaravi, Pedro; Carreres, Marcos; Peraza, Jesús E (SAGE Publications, 2018)

[EN] One of the test boundary conditions whose control is necessary for both experimental and numerical studies about the automotive engines research field is the temperature of the fuel inside the injector body during the ...
Engine combustion network (ECN): characterization and comparison of boundary conditions for different combustion vessels

Meijer, Maarten; Somers, Bart; Johnson, Jaclyn; Naber, Jeffrey; Lee, Seong-Young; Malbec, Louis Marie; Bruneaux, Gilles; Pickett, Lyle M.; Bardi, Michele; Payri Marín, Raúl; Bazyn, Tim (Begell House, 2012)

The Engine Combustion Network (ECN) is a worldwide group of institutions using combustion vessels and/or performing computational fluid dynamics (CFD) simulation, whose aim is to advance the state of spray and combustion ...
Engine combustion network: comparison of spray development, vaporization, and combustion in different combustion vessels

Bardi, Michele; Payri Marín, Raúl; Malbec, Louis Marie; Bruneaux, Gilles; Pickett, Lyle M.; Manin, Julien; Bazyn, Tim; Genzale, Caroline (Begell House, 2012)

Development and mixing of Diesel sprays are long known to be key factors for combustion and pollutant emissions but the related measurements in a real engine is not an easy task. This fact led researchers to simulate ...
Estudios experimentales mediante técnicas ópticas de las características de sprays para motores dual-fuel

Nareddy, Varun Reddy (Universitat Politècnica de València, 2017-07-27)

This work presents two experimental studies for characterization of injection sprays using experimental techniques as the fundamental tools. The first study focuses on the detailed understanding of the mixing process and ...
Fuel temperature influence on diesel sprays in inert and reacting conditions

Payri Marín, Raúl; García Oliver, José María; Bardi, Michele; MANIN, JULIEN (Elsevier, 2012-03)

The detailed knowledge of the evaporationecombustion process of the Diesel spray is a key factor for the development of robust injection strategies able to reduce the pollutant emissions and keep or increase the combustion ...
Modelado CFD de la evolución de un chorro Diesel en condiciones de motor

Gil García, Irene (Universitat Politècnica de València, 2016-12-28)

El objetivo del trabajo es la realización de cálculos CFD para la simulación de la evolución de un chorro Diesel en condiciones de motor. El alumno empleará un código CFD libre, el OPENFOAM, y será el encargado de configurar ...
Modelling and validation of near-field Diesel spray CFD simulations based on the Σ -Y model

Desantes Fernández, José Mª; García Oliver, José María; Pastor, J.M.; Pandal, A.; Naud, B.; Matusik, K.; Duke, D.; Kastengren, A.; Powell, C.; Schmidt, D.P. (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] Diesel spray modelling still remains a challenge, especially in the dense near-nozzle region. This region is difficult to experimentally access and also to model due to the complex and rapid liquid and gas interaction. ...
