Addendum: Axial Air flow Theory—Continuum Models

Abstract

In contrast to the previous chapters the present chapter has nothing to do with aircraft! It is presented more as an addendum devoted to the currently emerging non-aircraft areas of application of aeroelastic flutter such as for a biomedical application “palatal flutter” [102, 105] where the air flow is axial in contrast to normal. And piezoelectric power harvesting from wind as alternate energy source [106, 109] where the orientation of the structure with respect to the flow whether normal or axial is left open as part of system optimization. Both involve the dynamics of a structure modeled as a plate or beam in an air stream and the main interest is again in the aeroelastic flutter phenomenon. But this time our objective is not to suppress it but rather to maintain it, as in the power harvesting application.
