A new approach to compute temperature in a liquid-gas mixture. Application to study the effect of wall nozzle temperature on a Diesel injector

Payri, Raul; Gimeno, Jaime; Marti-Aldaravi, Pedro; Alarcón-Herrera, Mary Yilbary (Elsevier, 2017)

[EN] Thermal effects on internal combustion engines have been always a hot topic. Its effects also on the injection system are still under research. In this work, a homogeneous model called Eulerian Spray Atomization (ESA) ...
Analysis of spray/wall impingement using an ECN single-hole injector and a controlled-temperature wall under realistic engine conditions

Peraza, Jesús E; Payri, Raul; Gimeno, Jaime; Carvallo-Garcia, Cesar (Elsevier, 2022-05-25)

[EN] Spray¿wall interactions (SWI) directly affect fuel¿air mixture and emissions formation. Therefore, they are considered among the most critical physical processes in engine research nowadays. However, the physics of ...
Analysis of the interaction of Spray G and in-cylinder flow in two optical engines for late gasoline direct injection

Geschwindner, Christopher; Kranz, Patrick; Welch, Cooper; Schmidt, Marius; Bohm, Benjamin; Kaiser, Sebastian A.; De La Morena, Joaquín (SAGE Publications, 2020-01)

[EN] An investigation of the interaction between the in-cylinder flow and the spray topology in two spray-guided direct injection optical engines is reported. The bulk flow field in the combustion chamber is characterized ...
Application of an unsteady flamelet model in a RANS framework for spray A simulation

Desantes, J.M.; García-Oliver, José M.; Novella Rosa, Ricardo; Pérez-Sánchez, Eduardo Javier (Elsevier, 2017)

[EN] In the present investigation the Spray A reference configuration defined in the framework of the Engine Combustion Network (ECN) has been modeled by means of an Unsteady Flamelet Model (USFM) including detailed ...
ECN Spray D visualization of the spray interaction with a transparent wall under engine-like conditions, Part II: Impinging spray combustion

Peraza, Jesús E; Payri, Raul; Gimeno, Jaime; Marti-Aldaravi, Pedro (Elsevier, 2022-01-15)

[EN] In spite of the ever more comprehensive studies on diesel combustion, there is still an important gap on the fundamental knowledge about the interaction of fuel sprays with the piston and cylinder walls in internal ...
ECN Spray D visualization of the spray interaction with a transparent wall under engine-like conditions. Part I: Non-reactive impinging spray

Peraza, Jesús E.; Salvador, Francisco Javier; Gimeno, Jaime; Ruiz-Rosales, Santiago (Elsevier, 2022-01-01)

[EN] The possibility for a jet of fuel to collide against the surfaces of the combustion chamber or the piston bowl into a thermal engine, has a direct effect on the droplets breakup and the spray atomization. In order to ...
ESTUDIO CFD DE LA INYECCIÓN Y MEZCLA DE HIDRÓGENO EN MOTORES DE COMBUSTIÓN INTERNA ALTERNATIVOS SIGUIENDO LAS DIRECTRICES DE LA ENGINE COMBUSTION NETWORK

Carratalá Bañón, Sara (Universitat Politècnica de València, 2023-09-06)

[ES] El hidrógeno verde, y en concreto su combustión, se presenta actualmente como la gran alternativa al uso de combustibles líquidos en la generación de potencia, también en automoción. Es por ello que la Engine Combustion ...
