Abstract
The stability of thin liquid films on airfoils is studied using high Reynolds number ( Re) theory, for small disturbances. Two formulae, in closed form, for the linear growth rate and phase velocity of the disturbances in terms of the wavenumber and other relevant parameters are obtained from the analysis. Some parametric results are given. Numerical verification of these formulae is carried out by direct numerical integration of the ensuing set of nonlinear governing equations. Some preliminary applications are presented and comparisons with other available known results, either theoretical or experimental, are also provided.
