🔍 Key Concepts

• Heat transfer in stationary turbine rotors (conduction vs convection) • Where clearances are tightest between rotating and stationary parts in a turbine • Thermal expansion effects when metal heats unevenly in a non-rotating turbine

💭 Think About

• Think about which part of the turbine has the smallest clearances and is most sensitive to localized heating when the rotor is not turning. • Consider where heat can build up fastest if there is little or no movement to spread it around the rotor. • Ask yourself: which location, if overheated locally, would be most likely to cause rubbing or distortion between rotor and casing?

✅ Before You Answer

• Identify which option represents an area of close mechanical fit between hot stationary and cold rotating parts. • Eliminate options that are mainly flow path outlets rather than tight fit or sealing areas. • Focus on the place where local expansion or distortion would be most critical to turbine operation.
