A Comparison of Two Methods of Linearized Characteristics for a Simple Unsteady Flow

Abstract

Two methods of using the concept of linearized characteristics are derived for the one-dimensional unsteady flow in a tube that is rotated about an axis perpendicular to the axis of the tube. One of the methods corresponds to that used by Ferri in his basic work on the subject. Solutions are made by both methods for boundary conditions that allow analytic solutions. Comparison shows that both methods give the same results but there are significant differences in their application.
