Various groups have contributed data at the standard Spray G operating condition. While not being inclusive to all of this effort, several of the key datasets used for ECN workshops and CFD modeling comparison are listed here. The injector is AV67-028 unless otherwise stated.

Data collected previously for liquid penetration for the gasoline Spray G condition was presented in Manin 2015 (Manin et al., SAE 2015-01-1894). The liquid penetration was defined as that with an optical thickness of 0.6 in this work, which is inconsistent with the new ECN standard for liquid penetration length. Also, the data included beam-steering artifacts as discussed in Manin 2015. This data is not recommended for further use but is included here are available to download for documentation.
