Abstract
This paper presents a theoretical investigation of a wateraugmented
turbofan engine, one in which large quantities of sea water
are injected into the fan duct section. Results indicate that up to
three or four times dry thrust and propulsive efficiency are obtained
depending on vessel speed, fan pressure ratio, and amount of water
injected „ Optimum water injection velocity is investigated. Deviations
from thermal and dynamic equilibrium in the mixing processes are
investigated with respect to their effect on overall performance.
