Rayleigh condition

WebRayleigh's inflexion-point theorem: A necessary condition for instability is that the basic velocity profile should have an inflexion point. Proof: Write Rayleigh's equation in the form. (12) and suppose that so that the equation is non-singular. Multiplying by , integrating from to (using BCs and integration by parts) we have. Webputational power, we can now utilize reliable condition indicators (CI), which are computationally expensive. The potential of blind filtering for enhancing the fault detection capability of a complex condition monitoring indicator is investigated. The coefficients of the blind filter are optimized through the generalized Rayleigh
