181. When a turbine rotor is not rotating during maneuvering, the heat tends to be concentrated at the __________.
When a turbine rotor is stationary, heat concentrates at the top of the turbine due to convection. Without rotation, there is no circulation to equalize temperatures, causing the upper area to become hotter than the lower area. This uneven heating can lead to rotor distortion, necessitating slow rotor turning to maintain uniform temperature distribution.
