Analysis of transient liquid and vapor phase penetration for diesel sprays undervariable injection conditions

Pastor Soriano, José Vicente; Payri Marín, Raúl; García Oliver, José María; Briceño Sánchez, Francisco Javier (Begell House, 2011)

The objective of this study is to investigate liquid length and vapor penetration for diesel sprays under highly transient injection conditions. High-speed Mie-scattering and shadowgraphy imaging of the spray evolution ...
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 ...
Needle lift profile influence on the vapor phase penetration for a prototype diesel direct acting piezoelectric injector

Payri, Raul; Gimeno, Jaime; Viera, Juan P.; Plazas Torres, Alejandro Hernán (Elsevier, 2013-11)

In this study, Schlieren visualization tests have been performed for a prototype diesel common rail direct-acting piezoelectric injector, to understand the influence of fuel injection rate shaping on the vapor spray ...
Optical study on characteristics of non-reacting and reacting diesel spray with different strategies of split injection

Desantes, J.M.; García-Oliver, José M; García Martínez, Antonio; Xuan, Tiemin (SAGE Publications, 2019-08)

[EN] Even though studies on split-injection strategies have been published in recent years, there are still many remaining questions about how the first injection affects the mixing and combustion processes of the second ...
The effect of nozzle geometry over ignition delay and flame lift-off of reacting direct-injection sprays for three different fuels

Payri, Raul; Viera-Sotillo, Juan Pablo; Gopalakrishnan, Venkatesh; Szymkowicz, Patrick (Elsevier, 2017)

[EN] The influence of internal nozzle flow characteristics over ignition delay, and flame lift-off of reacting direct-injection sprays is studied experimentally for three fuels using two different nozzle geometries. This ...
The effect of nozzle geometry over the evaporative spray formation for three different fuels

Payri, Raúl; Viera-Sotillo, Juan Pablo; Gopalakrishnan , Venkatesh; Szymkowicz, Patrick (Elsevier, 2017)

[EN] The influence of internal nozzle flow characteristics over the evaporative spray development is studied experimentally for two different nozzle geome-tries and three different fuels. This is a continuation of previous ...
