WebThe Rayleigh principle • In chapter 8 it is proved that the Rayleigh quotient has a stationary point at the first eigenvector, it can be proven that it is a minimum • Because the Rayleigh quotient is flat near a minimum, substantial errors in vibration modes translate to only small errors in frequency 2 11 min ( ) 1 Y λω== RY= WebRayleigh flow is the specific case of frictionless flow in a constant-area duct, with heat transfer. Rayleigh flow applies to constant-area heat exchangers and combustion chambers where the entropy changes due to heat transfer are significantly larger than those due to friction: so we can neglect frictional effects and say d s ≈ d s e.
