An analysis on the hydrodynamic instability of two-phase flow in parallel multichan-nels is conducted.<BR>Occurrence of instabilities and their modes of oscillations can be evaluated by in-vestigating into a characteristic equation, its roots and composing channel transfer func-tions. It is also shown that a governing matrix is reduced to a diagonal one by using its eigenvalues, the oscillation modes being divided into N (number of channels) separate fundamental modes. Characteristics of each oscillation mode are given by examining corresponding characteristic equations.<BR>The derived equations are applied for the prediction of oscillation modes of systems composed of a few slightly different channels. The analysis successfully predicts the modes which have been experimentally observed.
