dc.description.abstract 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 engine conditions in special facilities that allow the use of high-fidelity diagnostics. The Engine Combustion Network (ECN) has focused on overcoming the variability from one institution to the next by testing nominally identical Diesel injectors in four different facilities for the first time, including constant-pressure flow and constant-volume preburn chambers. Liquid- and vapor-phase penetration, ignition delay, and lift-off length measurements are compared with similar experimental setups and processing methodologies. The consistency of the data obtained indicates a good level of repeatability between the test rigs employed, and no deviation of the results can be associated with the facility type. Comparison of liquid length measurements via Mie scattering shows that this diagnostic is sensitive to the orientation of the light source. For more repeatable results between facilities, diffused back-illumination imaging is recommended. A novel image processing method has been employed to detect spray boundaries obtained in high-speed schlieren imaging: the method showed high accuracy and robustness to the different schlieren setups employed by the institutions. High-speed broadband chemiluminescence, as schlieren imaging, shows the onset of cool flame, and moreover when the combustion is stabilized, it provides an important reference to define ignition delay and lift-off length. The methodology put in place by the ECN participants in this work allows an important step forward in two directions. The first is to understand the repeatability related to experimental data in high-pressure, high-temperature environments. The second is to advance the understanding of the different diagnostics applied, thereby providing more quantitative measurements that yield to a more suitable datasets for computational fluid-dynamic model evaluation. es_ES
