This thesis investigated the properties of a steam injector to see
if the concept might be suitable for use on a liquid rocket engine.
A steam injector is a device developed in the 1850's and was used
to inject feedwater into the boiler on a steam locomotive without
any moving parts. The injectors used a small portion of the steam
generated in the boiler to increase the pressure of the feedwater
to a level higher than the pressure in the boiler. Previous
experimenters claim that condensation of steam to water was
necessary for an injector to work. This experiment tested injection
without condensation using one of AFIT's wind tunnels. Compressed
air was used to simulate steam and liquid ethanol was used in place
of water. Pressure measurements were taken at points along the
tunnel to determine the performance of the tunnel. Results show
that this type of injection produces a small pressure rise compared
to tests without liquid injection. However, the exit pressure is
still lower than the initial pressure. Further testing is
recommended to analyze various parameters such as high temperature
flows and injector size.
