Experiment investigation on transient heat transfer in rotor-stator system with high-positioned air inflow

  • A gas turbine disk was simplified to be a shrouded rotor-stator system with high-positioned air inflow, the rotor was heated at rim. The rotor diameter was 400 mm and its maximal rotating speed was up to 3000 r/min. Transient heat transfer characteristics of the rotor were investigated experimentally as the rotational Reynolds number and the mass flow rate were changed. The results show: the mass flow rate could always have significant effects on average Nusselt number of the rotor. The rates of temperature vs. time in everyplace are almost same. The rotational Reynolds number has a few effects on averaged Nusselt number in this experimental range. The rate of temperature vs. time at high radius is large than that at low radius under different changes of rotational Reynolds number.
