The purpose of this is to make clear the flow instability problem in two-phase flow systems. In this first report, an experimental study was conducted on the oscillatory flow instabilities in an airwater two-phase flow system with upstream compressible volume. The flow pattern during the oscillation and the effects of the compressible volume and the average superficial velocity on the limit cycles were investigated. The periods of the oscillations were well correlated by two characteristic parameters obtained from a simple non-linear analysis.
