Abstract
Ethyl alcohols have been promoted as prominent renewable alternative fuel due to its advantageous properties like high heat of vaporization and high octane number. In this study, the spray behavior of ethanol fuel was investigated using a high-pressure gasoline direct injection system. Spray penetration length was evaluated at different input conditions. The research was carried out for the injection pressure of 3–11 MPa, 1–5 ms injection duration. Spray images were captured using Olympus high-speed camera at 10,000 fps, and these images were analyzed using an image analysis software Image J. The CFD simulation was also carried out using Ansys Fluent 19.2 software tool. The results obtained with simulation were found in good agreement with the experimental results by 7% of error. The empirical correlations were developed for spray penetration length. Spray penetration length for was found 141 mm, at 11 MPa injection pressure. These results were also validated with the CFD simulation. The maximum error in empirical co-relation and experimental results were found at 9.18%.
