Abstract

This study is to measure the impact pressure of supersonic liquid fuel jets injected in quiescent air at various stand-off distances from the nozzle exit. The main focus is to investigate the effect of different liquid fuel jets on the impact pressure. In this study, the supersonic liquid fuel jets are generated by the impact of a projectile, which known as impact driven method, launched by a horizontal single-stage gas gun (HSSGG). The impact pressures of the jets were measured by the PVDF pressure sensor. Moreover, the impact pressures were calculated from the water-hammer equation in order to compare with the measurement. From comparison, the impact pressure of all jets calculated from the equation and the measurement were different. From the measurement, the impact pressures of all jets decrease as the stand-off distance increases. The maximum impact pressure of diesel, kerosene, gasoline and alcohol jets is 662.37, 606.60, 559.50 and 699.5 MPa, respectively. Besides, it was found that the density is significantly the physical property of jet-impact pressure. The surface tension and the kinematics viscosity are significantly the physical property for the trend of jet-impact pressure against the stand-off distance.
