Siemens Research Engineer Interview Questions and Answers

Thermo-acoustic instabilities are oscillations in gas turbines caused by the interaction between combustion and acoustics.

• Occurs when the heat release rate and the acoustic modes of the combustor are coupled

• Can lead to high-amplitude pressure oscillations that can damage the turbine

• Can be mitigated by altering the geometry of the combustor or by using active control methods

• Examples include the Helmholtz resonator and t
