Final Report
Description:

The effect of antimisting kerosene AMK on jet pump performance has been determined experimentally. It is shown that the performance of the jet pump is reduced by AMK as much as 50 percent as compared to Jet A under identical operating conditions. Tests with the boost pump driven motive flow showed an improved performance. Low temperature AMK fuel resulted in an additional improvement on performance. Flow visualization and surface pressure measurements indicate suppression of turbulent mixing within the pump to be the cause for the reduced performance. In order to improve the efficiency of jet pumps with AMK, length of the mixing chamber was increased. With increased mixing chamber length, an improvement in mass transferred rate of 15 percent at a 2 psi pressure head was observed. Alternatively, larger size pumps designed to operate with Jet A are also proposed. Scaling parameters are given to dimension the pump using Jet A data. Water ingestion tests showed no precipitate formation prior to the entrance to the pump. As the flow moved through the pump, large amounts of precipitate were formed. This precipitate did not impair the operation of the pump.
