The coupling simulation method of flow and transient heat transfer with asynchronous steps was studied. CFX was used to simulate the flow and temperature distribution during 20 h after engine shut-down by using a civil high-bypass-ratio turbofan engine model. Result showed asynchronous steps ac-celeration method provided great accuracy and simulation cost. After shutdown, the circumferential temperature difference increased first under the influence of natural convection, and then decreased gradually. The temperature rise of positions like rotor disc bottom and bearing was significant because of heat soak back. To a certain extent, blowing cold air and barring gear was efficient in reducing non-uniformity of circumferential temperature and peak temperature in shut-down process.
