This project investigates a method for improving the energy transfer efficiency of "direct-flow induction" processes through enhancement of the single nondissipative component that is the work of interface pressure forces. This is achieved by imparting a transverse motion to paddle-like jets of the energizing fluid without, however, imparting the same motion to the fluid particles that make up the jets themselves and, hence, at no energy cost except for frictional losses. The transfer of momentum and energy from these "fluid paddles" to the flow to be induced will take place in good part through the work of the pressure forces that the two flows exert on one another at their moving interfaces. Use of this mechanism can be expected to lead to the development of improved jet pumps and thrust- or lift-augmenting ejectors.
Potential Commercial Applications: Applications would occur in thrust or lift augmenters for airliners and general aviation, improved water jet thrusters for marine propulsion, improved ejector pumps, and fuel injectors for scramjets.STATUS: Phase I Only
