Predictions of liquid fuel injector performance with gaseous fuels

摘要

A method to predict the maximum flowrate of a liquid fuel injector when operating with gaseous fuelshas been developed. Three injectors were tested for flow capability with four gases of variousmolecular masses and ratios of specific heats. Compressible flow theory has been used to non-dimensionalize the results, and predictions have been made for performance with other gases andmixtures.
