In order to realize the stable operation of the kerosene/oxygen-enriched air rotating detonation combustion， the influence of total inlet temperature on the flowfield and combustion characteristics was explored. In this paper， a liquid kerosene/oxygen-enriched air rotating detonation combustor is designed. The non-reacting and reacting flowfied is simulated with the Euler-Lagrange algorithm. Results show that with the increase of the total inlet temperature， the fuel atomization and mixing effect shows a parabolic trend. At 1 150 K， the fuel evaporation rate is the highest （99.2%）， and the blending uniformity is 50.3%. Under the condition that the total inlet temperature exceeds 650 K， a stable rotating detonation wave can be achieved. The total inlet temperature has a significant impact on the propagation mode of the detonation wave. The total inlet temperature is beneficial for the formation of the multi-wave mode of detonation. With the increase of the number of detonation wave， the pressure， wave velocity and detonation wave height of a single wave decrease， and the stability of the overall detonation wave is significantly improved.
