    Abstract

    Transient disturbance growth in parallel two-phase flow is studied. When the disturbance growth is measured in terms of the kinetic energy norm, which is commonly used for single-phase flow, the disturbance growth function does not converge as the number of eigenmodes used in the computation increases. A solution to this problem is presented in the form of a norm that also includes the potential energy of the disturbed interface. This solution is used to examine the two-phase flow experiment by Kao and Park.
