AB - In this study, experimental methods are used to investigate the effects of different vibration and pressure parameters on heat transfer performance are analyzed. The results show that at a subcritical pressure (0.1 MPa), the external vibration begins to affect the heat transfer when the fuel passes the phase-change point and becomes gaseous. At a near-critical pressure (3 MPa), the external vibration deteriorates the heat transfer of fuel across the critical-temperature zone. At the supercritical pressure (5 MPa), the external vibration intensifies the heat transfer in the hot end of the channel only when the fuel is below the critical temperature and the internal wall is above the critical pressure. Combined with data analysis, it can be seen that the external vibration mainly acts on the temperature boundary layer of the fuel oil to affect the wall temperature and heat transfer coefficient.
