【 摘 要 】

A series of combustion rig tests were analyzed to determine liquid jet penetration heights of oil-in-water unsteady emulsions in a gaseous cross flow. Data was taken ranging the water to fuel ratio at several engine loads. The goal of this study is to develop a transfer function to model penetration heights over the engine load range and compare with emissions requirements to predict emission compliant water to fuel ratios without risk of combustion liner wetting and coating spallation. In this study correlations were developed at lower and upper range engine loads while the mid range shows an unclear transition pattern that needs to be addressed in further research.
