Abstract: 
To investigate the characteristics of vaporized kerosene combustion in a scramjet combustor enhanced by the micro vor-tex generator (MVG), a series of experiments are carried out based on the advanced combustion diagnosis technique. The high-enthalpy incoming flow is accelerated to supersonic through a Mach 2.52 nozzle, the total pressure and temperature of which are 1.6 MPa and 1486 K, respectively. The effect of micro vortex generator on the ignition process, flame distribution, and combustor pressure along the bottom wall is well revealed, and the effects of the position and number of micro vortex generators on stable combustion performance are analyzed. The results indicate that the development processes of the initial flame kernel with and with-out a micro vortex generator during ignition process show a similar behavior. The installation of a micro vortex generator can lift the shear layer, promote the penetration of flame deeper into the mainstream, and expand the area of the reactive region. Reducing the distance between the micro vortex generator and the injection position and increasing the number of micro vortex generators are regarded as effective ways of improving the mixing degree of fuel and air with a resultant intensification of chemical reactions and flame luminescence. The effect of mixing and subsequent combustion is enhanced by shortening the distance between the micro vortex generator and the injection position. As the layout schemes of the micro vortex generator vary, the pressure distribution between the injection position and the leading edge of the cavity changes considerably, while that in the cavity remains almost con-stant. Increasing the number of micro vortex generators is also beneficial for improving the premixed degree of fuel and incoming flow and results in more violent chemical reactions downstream of the cavity.
