Which of the following is not controlled mainly by dilution hole placement?

  • A.The exit temperature pattern
  • B.The peak exit temperature
  • C.The pattern factor
  • D.The weak extinction limit

Answer: D

Correct answer: The weak extinction limit

The weak extinction limit is a property of the primary zone - of the local mixture strength, the recirculation and the fuel preparation - and dilution holes are far downstream of it. What they do control is everything about the exit: the temperature pattern, its peak, and hence the pattern factor, which is why they are the feature adjusted during rig development.
