Summary
Tokamak fusion reactors will require a method for replenishment of spent fuel when operated in a steady-state mode. To establish the fueling requirements, a device capable of delivering a 1-mm-diameter hydrogen pellet at 2 km/s every 10 minutes is desired. This effort was to design, fabricate and test an experimental high-pressure fuel injector capable of producing pulsed liquid hydrogen jets of 2 km/s and 0.6 mm diameter. A device was tested in which hydrogen initially at pressures of up to 2 kbar and temperatures down to 35/sup 0/K, was expanded through a nozzle 0.65 mm in diameter and 46 mm long. Jet velocities were as predicted. The jets, injected into variable H2 pressure atmospheres, exhibited spiral patterns. Insufficient precision in the hardware causing nonsymmetric flow to the nozzle inlet is believed to have produced the spiral jets.
