Thermal and flow field in a rotor-stator system around a single stage HP-turbine disk are investigated. In the previous work, the authors’ group applied a newly developed conjugate analysis method to the system at a steady-state condition, compared the thermal field with the measured data, and concluded that a satisfactory level of accuracy can be achieved with the proposed method at the steady-state condition. The present paper focuses on a heat and fluid flow in the same rotor-stator system, but at a transient condition which simulates a typical accelerating and decelerating schedule expected in actual aero-engine operations. First, detailed measurement of secondary-air and metal temperatures around the turbine disk is carried out in the transient condition. Then, the 3D fluid / solid conjugate analysis is applied to the whole accelerating and decelerating schedule. The results show that the transient thermal behavior of the rotor-stator system is well captured and reproduced with the present conjugate method.
