Stability Analysis of a fluid in Horizontal and Inclined Channels

This paper is devoted to analysis the stability of horizontal and inclination in a glazing cavities of equations that we expose to disturbance. This analysis is done by finding the eigenvalues of the system which enable us to investigate the grow of disturbance after setting glazing cavities equations in linearization form. We obtain from our results that the equations are stable when the real part of wave velocity is negative , and unstable when it is positive .
