Comparative study of the internal flow in diesel injection nozzles at cavitating conditions at different needle lifts with steady and transient simulations approaches

Salvador, Francisco Javier; De La Morena, Joaquín; Crialesi Esposito, Marco; Martínez López, Jorge (SAGE Publications, 2018)

[EN] The motion of the needle during the injection process of a diesel injector has a marked influence on the internal flow, the fuel characteristics at the nozzle exit, the spray pattern and the fuel-air mixing process. ...
ESTUDIO DE LA INFLUENCIA DEL FENÓMENO DE LA CAVITACIÓN SOBRE EL FLUJO INTERNO EN TOBERAS DE INYECCIÓN DIESEL

Martínez López, Jorge (Universitat Politècnica de València, 2011-07-27)

El objetivo principal de la presente tesis es el modelado computacional de la cavitación en el interior de los orificios de las toberas de inyección Diesel durante el proceso de inyección, prestando especial atención a la ...
Large-eddy simulation analysis of the influence of the needle lift on the cavitation in diesel injector nozzles

Desantes Fernández, José Mª; Salvador Rubio, Francisco Javier; Carreres Talens, Marcos; Martínez López, Jorge (SAGE Publications (UK and US), 2015-03)

The cavitation phenomenon has a strong influence on the internal flow and spray development in diesel injector nozzles. Despite its importance, there are many aspects which still remain unclear, especially for partial ...
Linking instantaneous rate of injection to X-ray needle lift measurements for a direct-acting piezoelectric injector

Viera-Sotillo, Juan Pablo; Payri, Raul; Swantek, Andrew B.; Duke, Daniel J.; Sovis, Nicolas; Kastengren, Alan L.; Powell, Christopher F. (Elsevier, 2016-03-15)

Internal combustion engines have been and still are key players in today's world. Ever increasing fuel consumption standards and the ongoing concerns about exhaust emissions have pushed the industry to research new concepts ...
Study of the influence of the needle lift on the internal flow and cavitationphenomenon in diesel injector nozzles by CFD using RANS methods

Salvador, F. J.; Martínez López, Jorge; Caballer Fernández, Miguel; Alfonso Laguna, Carlos de (Elsevier, 2013-02)

It is well known that cavitation phenomenon in diesel injector nozzles has a strong influence on the internal flow during the injection process and spray development. However, its influence on the flow during needle opening ...
Study on Advanced Spray-Guided Gasoline Direct Injection Systems

Vaquerizo Sánchez, Daniel (Universitat Politècnica de València, 2018-03-22)

Resumen Los sistemas de inyección directa han sido uno de los principales puntos focales de la investigación en motores, particularmente en sistemas Diésel, donde la geometría interna, movimiento de aguja y comportamiento del ...
Transient flow simulations of Gasoline Direct injection (GDi) nozzles: nozzle flow and sprays

Martínez García, María (Universitat Politècnica de València, 2019-10-28)

[ES] En el campo de los motores de combustión interna alternativos (MCIA) el uso de la inyección directa de gasolina (GDi) ha ido ganando importancia durante los últimos años porque permite reducir el consumo de combustible ...
