The jet behaviors of supercritical RP-3 aviation kerosene injected with a pressurized quasi-quiescent air were experimentally investigated. Under the ambient pressure of 0.15—1.02 MPa, the near-nozzle macroscopic morphology of the supercritical RP-3 jets injected from a two-dimensional convergent nozzle was recorded by shadowgraph imaging. The results showed that supercritical RP-3 jets underwent an underexpanded jet process similar to that of an ideal-gas, exhibiting visible barrel shock structures. The physical interpretation performed through the thermodynamic phase diagram of a 10-component RP-3 surrogate showed that supercritical RP-3 jets underwent one or more isentropic expansion, entropy-increasing compression and isobaric mixing processes within the near-nozzle region. With the increase of the ambient pressure, the jet morphology of supercritical RP-3 changed from a very highly underexpanded state to a highly underexpanded state, and the jet expansion angle, the diameter of the first cell, and the position and diameter of the first cell Mach disk all decreased gradually.
